Not quite a puffball

Stalked Puffball-in-Aspic may sound like a puffball, but it isn’t. Long mistaken for a puffball, earthstar, or stinkhorn, Calostoma cinnabarinum is now classified in the order Boletales, despite little resemblance to its relatives. Its name “cinnabarinum” comes from the Greek kinnábari, for its vivid cinnabar-red color, like dragon’s blood. Common names include red slimy-stalked puffball, aspic puffball, gelatinous-stalked puffball, and “hot lips.” In central Mexico, it’s called “orchid fungus” in Spanish (hongo orquídea) and Nahuatl (huang noono).

A fungi defined by its slime

A key trait of this mushroom is its “aspic”, a gelatinous veil that surrounds the young fruit before sloughing off. The goo has been compared to amphibian eggs or “small red tomatoes in jelly.” As it matures, a whitish stalk emerges while the red tip elongates and fades. Mycorrhizal with oaks, it grows alone or in groups, often in moss beds or wet lowlands, from spring through fall. Its range includes eastern North America, Texas, possibly the Southwest, as well as Central and South America, with reports from Asia. It’s especially common at higher elevations; the described collections are from North Carolina.

Can you eat it?

Few would be tempted to eat this mushroom, and most field guides list it as inedible. Yet a study of mestizo descendants of the Otomi people in Tenango de Doria, Mexico, found that immature specimens, called yemitas, were once eaten raw—especially by children—though this is no longer common. The gleba is described as mild in taste, not sweet despite local recollections. A 1986 ethnomycological study in Veracruz recorded its use to treat gastrointestinal distress. Still, other folk beliefs warn it is poisonous, citing its bright color as a sign of danger.

August Mushroom of the Month: Blushing Rosette, Abortiporus biennis

The August Mushroom of the Month is the The Blushing Rosette, Abortiporus biennis

🍄⭐The August mushroom of the month is the Blushing Rosette, Abortiporus biennis

👏 Congrats to Sophia for guessing it right and winning a membership to the society! 🎉

You can also be a supporting member to stay dialed-in with events & discover next month’s mystery mushroom.

Blushing Rosette

Abortiporus biennis — the blushing rosette - is a rare but charismatic bracket fungus that has a soft spot for our local oak and elm trees. Around East and Central Texas, you might spot it fruiting in spring or fall, usually on dead or dying branches. Its brackets are semicircular to kidney-shaped, with a smooth, velvety top and a pore surface that glows white to cream.

Two distinct forms of Abortiporus biennis can be encountered: a "normal" looking, regular sort of polypore with a brown cap and a whitish pore surface that bruises reddish to reddish brown—and a gnarled, messy-looking, "aborted" form that consists of a mass of irregular white pores that exude a reddish juice and bruise reddish brown; in this form there is hardly a cap or a stem to speak of, and as the mushroom grows it often engulfs sticks and blades of grass.

A Tricky Taxonomy

Taxonomists have had quite the time with Abortiporus. There are at least 55 different names it’s gone by — a mix of species and genus labels — thanks to its wildly different forms. They can look so unlike each other (and unlike other polypores) that early mycologists kept thinking they’d discovered something new. To make matters even more interesting, Abortiporus biennis produces both sexual spores and asexual chlamydospores, which led to its anamorphic forms getting their own separate names.

Why We Love It: This is a fungus with a serious flair for disguise. It’s a living example of why mushroom ID can be equal parts science, art, and wild goose chase — and we’re here for it.

Tips for ID

Cap: 5–15 cm across; roundish-to semicircular, kidney-shaped, or irregular in outline; planoconvex; finely to thickly velvety, or sometimes more or less bald; dry; light brown to reddish brown or tan, with a pale margin; sometimes with concentric zones of brown shades.

Pore Surface: Whitish, bruising and discoloring reddish or pinkish brown; pores appearing "stuffed" when young, later angular to maze-like or irregular, 1–4 per mm; tubes to 5 mm deep.

Stem: When present 3–10 cm long; 1–3 cm thick; lateral; tapering to base; soft and spongy; fuzzy; brownish.

Flesh: White to pinkish or pale tan; exuding a pinkish juice when squeezed; tough.

Odor: Fragrant or, often, somewhat foul.

Chemical Reactions: KOH on flesh negative to pale brown.

Spore Print: White.

July Mushroom of the Month: Purple-spored Puffball, Calvatia cyathiformis

The July Mushroom of the Month is the Purple-spored puffball, Calvatia cyathiformis

puffball gigante

Two grapefruit-sized puffballs bloom in the grasslands of North America: the Giant Puffball, Calvatia gigantea, and the Purple-spored Puffball, Calvatia cyathiformis. Both are edible when young—their interiors pure white and marshmallow-soft. What distinguishes the Purple-spored from its cousin is its transformation with age—body and spores evolving from pure white to deep, rich purple. In East and Central Texas, it fruits June to October, often in open woods, fields, and roadsides. The fungus grows in various soils, including clay, loam, and sand, and is associated with oak, pine, and other deciduous trees

taxonomy & ecology

Calvatia cyathiformis, or purple-spored puffball, is a large saprobic Calvatia species. This terrestrial puffball has purplish to purple-brown spores, distinguishing it from other large Agaricales. The fruiting body is 5–20 cm (2–8 in) high or broad. When young it’s smooth, spherical or slightly flattened, and white, purplish, or brownish. It has a chocolate-brown or purple gleba with a smooth exoperidium. As it matures, it becomes pear- or top-shaped, and the exterior darkens or silvers. Later, the skin cracks, releasing spores dispersed by wind and rain. A leathery sterile cup remains after spores disperse.

uses & benefits

Besides being edible when young, puffballs can be used to dye fabrics and paper when used in combination with ammonia (as a mordant). Purple-spored Puffballs create a rusty red color while Giant Puffballs make a more reddish-brown dye. Medical scientists are currently investigating puffballs in the genus Calvatia because they have been shown to prevent some types of tumors. For years, puffballs have been used as a styptic to stop bleeding and to dress wounds − both powdered and slices of the mushroom.

June Mushroom of the Month: White Juniper Fungus, Robergea albicedrae

The June Mushroom of the Month is White Juniper Fungus, Robergea albicedrae

👏 Congrats to Reid Hardin @ireidaceae for guessing it right and winning a membership to the society! 🎉

it’s not chalk, it’s not mold, it’s a lichen!

It’s a common sight in the Texas hill country, one you might have even overlooked or never thought to take much notice of - the branches of ashe juniper trees striped with a non descript, chalky white material. At first glance it looks like it could be part of the tree itself, just some variation of the bark. It’s prolific. Upon closer inspection, you may notice some small nodules, or fruiting bodies, from which spores are expelled. What you are looking at is, in fact, a lichenized fungus!

Taxonomy & Ecology

Lichens are symbionts, a symbiotic relationship between an algae and a fungus. They are classified by their fungal partner. In 1910, Heald and Wolf described this fungus species and assigned it the name Cyanospora albicedrae. The generic name Cyanospora was based on the (apparently incorrect) observation that the spores were green. The following year Saccardo and Traverso corrected this and assigned the species to the genus Robergea.

When you see this fungus in the field, look for small gray nodules on the whitened patches. These contain the fruiting bodies from which the filamentous spores

are expelled.

Juniper Friend or foe?

Since its description in 1910, many researchers have assumed that the relationship between Robergea albicedrae and its host to be parastic. However, studies of others in Stictidaceae have shown a dynamic relationship in terms of nutrient assimilation, for example, the colonization of existing dead twigs as saprotrophs, “optional lichenization,” and parasitic endophytism. More research is needed to determine the exact nature of their relationship.

  • Not a choice edible but young mushroom has a mellow, earthy flavor. Must be cooked.

Look-alikes: Strobilomyces confusus (non-toxic) or Amanita onusta (Toxicity unknown)


HONEY MUSHROOMS

Desarmillaria, Armillaria species

Honey-colored, dry, scaly to sticky cap, Mellea species has a ring on the stem. Grows in clusters and has gills. Part of a genus that is the largest living organism ever found on this planet.

SPORE COLOR: White

HABITAT: Decaying hard-wood stumps and roots of living trees in the spring and fall after rain.

SIZE: 6"

EDIBILITY: Choice. Many species emit a fruity aroma, reminiscent of apricots, and often have a mildly peppery taste.

LOOK A-LIKE: The Southern Jack-o-lantern, Omphalotus subilludens is the toxic look-a-like and is orange to brown in color. They do grow at the same time but their habitat and morphology is different.


Jackson's Slender Caesar

Amanita jacksonii

CAP: Emerges from egg or volva and is oval at first, becoming convex, typically with a central bump; sticky; brilliant red or orange, fading to yellow on the margin; typically without warts or patches; the margin lined for about 40–50% of the cap's radius. The red pigment fades from margin toward the center with age.

GILLS: Moderately crowded to crowded, orange-yellow to yellow-orange to yellow. They are free from the stem or slightly attached to it; yellow to orange-yellow; crowded; not bruising. The short gills are subtruncate to truncate.

STEM: 9-15 cm long; 1-1.5 cm thick; slightly tapering to apex; yellow; with orange to reddish fibers, often in zones; not bruising; with a yellow to orange, skirtlike ring; with a large (4-7 cm high and 4 mm thick), white, sacklike volva.

SPORE COLOR: White

HABITAT: Mycorrhizal with in hardwoods and pines. They are more common in East Texas but they can be found in Central Texas in places like Bastrop

SIZE: 3-4" in height. Caps sometimes open to 6-10”.

EDIBILITY: Choice but not recommended because of toxic look a-likes. The flavor is of hazelnuts and chestnuts.

LOOK A-LIKE: A. muscaria (contains a neurotoxin that can be parboiled out and A. phalloides (fatal).


honeycomb fungus

Favolus

Genus of tropical fungi in the family Polyporaceae but with fleshy with radially arranged pores on the underside of the cap that are angular and deeply pitted, somewhat resembling a honeycomb. White to yellow and grows alone or in overlapping clusters similar to oyster mushrooms or other shelf fungi.

SPORE COLOR: White

HABITAT: On decaying hard-wood, year round when humidity is high after rain.

EDIBILITY: Odor slightly foul, especially in rehydrated material; taste not distinctive. Tough texture and can be cooked like chicharrones.

LOOK A-LIKE: Oysters, Pluerotus or Lentinellus cochleatus (none observed in Texas) but grow on decomposing wood.


Shoehorn Oyster Mushrooms

Hohenbuehelia petaloides

Pale to brown funnel-shaped caps with decurrent gills

SPORES: White

HABITAT: Fruits after rain in mulch or woody debris. Considered carnivorous because it traps nematodes with “sticky knobs” in the mycelium to obtain nitrogen and grow.

EDIBILITY: Edible when cooked but can be tough and mealy

Shoehorn Oyster Mushrooms, Hohenbuehelia petaloides is distinctively shaped; its "petaloid" habit often makes it look like a shoehorn with gills, or a rolled-up funnel. Other identifying features include its fairly crowded whitish gills, a white spore print, mealy odor and taste—and, under the microscope, gorgeous "metuloids" (thick-walled pleurocystidia). It often appears in clusters in urban, semi-urban, or even household settings, and is frequently associated with woody debris (though it does not usually grow directly from dead wood) or cultivated soil. However, it can be found in woodland settings, too, where it tends to grow alone or in small groups.

Because this mushroom grows in wood chips which are a good source of carbon but a terrible source of nitrogen, the fungi needs to make proteins. Both Hohenbuehelia and Pleurotus can supplement their protein needs by trapping and consuming nematodes, which are small flat worms that are very abundant in wood and soil. The fungi have "sticky knobs" on the hyphae that grow through the wood. These sticky knobs attach to curious nematodes as the nematodes attempt to eat the mycelium. The nematode thrashes around and additional parts of its body become stuck. The hyphae then grow into the body of the nematode and digest it, providing the fungus with the nitrogen it needs. That makes these fungi carnivorous!

LOOK A-LIKES: Oysters, Pluerotus or Lentinellus cochleatus (none observed in Texas) but grow on decomposing wood.


WOOD BLEWIT Collybia species, formerly Lepista, Clitocybe

  • Distinct lilac to purple-pink color

  • Grows in and decomposes leaf duff

  • Light pink to white spores

  • Great in breakfast tacos

As the weather stays cool, look out for the edible Wood Blewit, Collybia nuda or tarda species (formerly Lepista and Clitocybe.) This distinct lavender-colored mushroom is found from fall through spring and fruiting in hardwood leaf duff which is decomposes. Fresh wood blewits are great with eggs in breakfast tacos. As they get older they become more tan and iridescent colored on the cap and taste bitter. I throw the older wood blewits my compost leaf pile because they are such great decomposers and will colonize and grow in hardwood leaf litter.

Look-alikes: Be warned because there are deadly, poisonous look-alikes in the Cortinarius or webcap family that grow in similar conditions. It's important to do a spore print AND also confirm the ID with an expert. The spores of the wood blewit are light pink to white and the spores of Cortinarius mushrooms are rust colored. See our blog post with lots of photos and details to help you identify this mushroom.


OYSTER Pleurotus ostreatus

  • Color can vary white, tan and gray

  • White to cream gills, run down stem

  • Cap fan shaped, 2"-8" across, white spores

  • Grows in clusters and decomposes hardwood

  • Delicious meat replacement in all types of cuisines

Look-alikes: Southern Jack-o-lantern, Omphalotus subilludens which is toxic and orange to brown in color.


WOOD EAR: Auricularia species

  • Grows in clusters on decaying hardwood after rain

  • Cap is wavy, ear-shaped to irregular, 1-4" and > 1/4" thick

  • Jelly texture and lacks gills or pores

  • Produces white spores

  • Absorbs flavors, great in soups, contains protein, iron, calcium and phosphorus

Edibility: Wood ear mushrooms are a popular ingredient in many Chinese dishes, such as hot and sour soup, and also used in Chinese medicine. It is also used in Ghana, as a blood tonic. Modern research into possible medical applications has variously concluded that wood ear has anti-tumor, hypoglycemic, anticoagulant and cholesterol-lowering properties.

Look-alikes: Amber Jelly, Exidia recisa which is also edible.

How to Cultivate Bioregional Mycorrhizal Fungi for Plants

There are several types of mycorrhizal fungi, but ecto- and arbuscular mycorrhizal fungi (AMF) are the most common.

Instructions adapted from Danielle Stevenson, D.I.Y. Fungi, This content was taught at workshop with Danielle for Healthy Soils, Healthy Trees program and part of tree drought research with TreeFolks. Thanks to Ecology Action and City of Austin Urban Forestry Grant for supporting this program.

There are several types of mycorrhizal fungi, but ectomycorrhizal (EMF) and arbuscular mycorrhizal fungi (AMF) are the most common. It is a good idea to look up what kind of mycorrhizal relationships the plant(s) you’re trying to cultivate form and cultivate those.

Watch part one of our workshop series with Danielle to learn more about mycorrhizal fungi.

Do you need to restore mycorrhizal populations? Yes in:

  • intensively managed agricultural lands (industrial ag- frequently tilled, heavily

    fertilized, fungicide use)

  • degraded soils (remediation of mine sites and brownfields, ecological restoration and reforestation efforts)

  • nurseries (and hydroponic or container gardens)

You can restore mycorrhizal fungi through agricultural and land management practices or through introduction of  mycorrhizal inoculum. Management practices that encourage mycorrhizal fungi: 

  • Crop rotation including deep rooting of mycorrhizal plants

  • Cover cropping - do not leave soil bare 

  • Reduced/no till  

  • Deep plowing

  • Reduced fertilization (esp Phosphorus)

Where to source your MYCORRIZAL SPORES?

You can purchase commercial mycorrhizal spores to inoculate plants and soil but recent meta analysis has shown they are less effective than using methods that introduces native, cultivated mycorrhizae. Mycorrhizal spores, pieces of mycorrhizal roots and viable mycorrhizal hyphae are active propagules that can be used as inoculum.

Methods OF CULTIVATING AND AMPLIFYING Native mycorrhiza

  • Whole Soil Method

  • Trap Culture Method

  • Nurse Plant Method

  • Spore Slurry Method (EMF)

  • Species-specific AMF Method

Whole Soil METHOD

  • Takes soil from a healthy reference ecosystem as inoculum

  • It inoculates with intact rhizosphere soil containing the complete array of the soil community including AM fungi, beneficial bacteria such as nitrogen fixing Rhizobia, pathogens, soil-dwelling insects, nematodes, plant roots, and even seeds.

  • Destructive of healthy ecosystems and requires huge amounts of soil (150-10,000 gallons per acre).

Workshop series with Danielle at Circle Acres on how to cultivating bioregional mycorrhizal fungi using trap culture methods.

Trap Culture Methods

  • The following method is what we are using for our Healthy Soils, Healthy Trees research.

  • Works to amplify the volume of whole soil microbes so that a few liters of whole soil inoculum can be used to inoculate hundreds of plants.

  • Trap cultures are a way of ‘bulking up’ the AM fungal community present in whole soil before it is used as inoculum in a restoration. The AM fungi + plant dependent soil microbes are amplified by growing with plant hosts in a pot and this allows their propagation for future use.

Step-by-Step: Trap Method for Cultivating Native Mycorrhizal Fungi

Materials needed:

  1. Clean Nursery pots or fabric grow bags. (The size of the pot should consider the root depth of the host plant at maturity.)

  2. Native soil (from under healthy, mature trees)

  3. Sterile potting mix or compost (See DIY mix below)

  4. Host Plant Seeds: Bluestem, Corn, Sorghum

  5. Shade cloth or partial shade location

  6. Access to Water

  7. Optional: mesh or hardware cloth to deter critters

Collecting soil from mother trees in the winter.

1. Gather Native Soil: Collect small amounts of soil from mature, healthy native plants you plan to propagate. This soil contains mycorrhizal fungi, root fragments, and microbes — the soil microbiome.

2. Mix Native Soil with Coarse Sand: Combine at a 1:1 ratio by volume (not weight).

3. Mix Your Own Sterile Potting Soil (Optional): It is becoming more common for AMF or EMF fungi to be added commercial mixes of potting soil. To ensure you have a sterile potting soil, we recommend a blend of coco coir and vermiculite at a 1:1 ratio by volume.

4. Combine Native Mix with Sterile Soil: Mix the native soil and sand with the sterile mix at a 1:1 ratio. Fill into clean nursery pot/s. Exact ratios aren’t critical — what matters is seed contact with native soil.

5. Seed Host Plant into Pots: Use grasses like bluestem, corn, or sudangrass, which tolerate heat and rely on AMF. Overseed the pot.

6. Water Regularly: Keep soil moist but not soggy. Mimic natural rainfall. Use rainwater if possible.

7. Provide Shade: Place pots in partial shade to reduce seedling stress and encourage fungal growth.

8. Grow Host Plant for 3–6 Months: Over time, fungi from the native soil colonize the roots. You’re “farming” fungal partnerships.

9. Stop Watering and Let Plants Dry Out: Leave pots undisturbed for 2–3 weeks. This triggers the host plant to invest carbon into AMF. As it dies back, AMF sporulate. Then, cut the shoots at soil level.

10. Harvest, Store, and Use Inoculum: Harvest the soil or chop the roots and mix with clean sand. This root-sand mix is your concentrated AMF inoculum. Store in plastic containers in a cool, dry place — it remains viable for at least a year. Use it for new pot cultures, in potting mixes, or to inoculate “nurse” plants in the greenhouse or field. Apply it in gardens, restoration sites, or urban forests.

For the Healthy Soils, Healthy Trees research we will store all of the soil in 5 gallon pots indoors until it is time to plant trees in the late winter. Watch recording of workshop where we harvest the roots and validated that we cultivated AMF.

Low-Tech, In-Ground Trap Cultures: In-Ground Trap Cultures: Missouri Botanical Garden and the Restoration EcologyLab at Virginia Tech

  1. Fill a pit (150 cm long × 50 cm wide × 30 cm deep) lined with sacks with topsoil collected from around the roots of three native tree species

  2. Then grow maize and beans in this soil for three months before cutting these plants down

  3. Letting the substrate dry out for two weeks. The substrate remaining in the pit is the inoculum

  4. Use by adding one tablespoon inoculum to each seedling container.

The nurse plant method

  • Inoculating potted seedlings with AM fungi before planting into a site allows them to act as nurse plants

  • Enhances the likelihood that the inoculum will remain viable in the field

  • AM fungi can spread to nearby un-inoculated plants, over distances of up to two meters within a single growing season

SPORE SLURRY METHOD FOR Cultivating native Ecomycorrhizal fungi (EMF)

REQUIREMENT: Mushrooms (that you know are ecto) must be gathered from near known ecto-mycorrhizal fungal trees.

Spores or macerated fruiting bodies of some ectomycorrhizal mushrooms, puffballs, or truffles (and false truffles) provide good inoculum. Truffles (Ascomycotina) and false truffles (Basidiomycotina), from now on together referred to as truffles, are uniquely suited for this because their fruiting body tissue consists mostly of spore-bearing tissue and the fruiting bodies can be quite large. We recommend using fresh spores whenever possible, but have stored spore suspensions of various Rhizopogon species up to 3 years without a significant reduction in inoculum effectiveness (Castellano 1987).

  1. Rinse freshly collected fruiting bodies with tap water to remove adhering soil or organic matter

  2. Cut into pieces (1 - 3 cm) and blend with tap water at high speed for 2 to 3 minutes, until all pieces are thoroughly blended. Note: The final consistency is similar to thick chocolate milk.

  3. It is unnecessary to purify spore suspensions. Li and Castellano (1987) and Li (1987) have found beneficial microorganisms within and on the surface of mature fruiting bodies of various ectomycorrhizal fungi; these organisms should be encouraged, not excluded.

  4. Spore concentrations within the resulting suspension are determined with a hemacytometer (blood cell counter).

  5. Store slurry in the dark in the refrigerator until used (up to 3 years) at up to 5 °C or 41 °F).

To then inoculate plants:

  1. In a nursery or for nurse plants, apply spore slurry 6 to 12 weeks after sowing, either with a standard watering can or through the existing irrigation system. Most truffle spores are less than 50 μm in diameter and will pass freely through most filters and nozzle tips.

  2. The desired amount of spores is mixed into a watering can containing sufficient water to cover a certain number or area of seedlings (Styroblocks® or racks of plastic tubes).

  3. Applying spores twice, 2 to 3 weeks apart, works best to assure even distribution (fig. 5.2.53), especially when using the irrigation system instead of watering cans. Alternatively, spores can be applied to the seed before sowing. Although we have not tried this method, it may prove more effective than the watering can method in inoculating each seedling. Seed treatment would also allow finer control in matching ecotypes of fungi to specific seed sources.

Species-specific AMF method

Arbuscular mycorrhizal (AM) cultures contain only living propagules of single or multiple mycorrhizal fungal species). Cultures of a single species usually must be started from carefully selected spores. These spores can originate from a field soil if they are healthy.

May Mushroom of the Month: Silky Rosegill, Volvariella bombycina

The May Mushroom of the Month is Silky Rosegill, Volvariella bombycina

🍄⭐The May mushroom of the month is Silky Rosegill, Volvariella bombycina


🙌 to Monica for correctly identifying this mushroom and the newest member of the society.

pretty in pink

Volvariella bombycina—also known by a few charming names like silky sheath, silky rosegill, silver-silk straw mushroom, or tree mushroom—is an edible mushroom from the Pluteaceae family. It’s not super common, but it does show up in quite a few places around the world, including Asia, Australia, the Caribbean, Europe, and North America. You’ll usually spot it growing alone or in small clusters, often tucked into old knotholes or damaged spots on elm and maple trees. When it first appears, its gills are a bright white, but as it matures and the spores develop, they take on a soft pinkish hue.

Taxonomy & Ecology

The fruit bodies of Volvariella bombycina are initially egg-shaped when still enclosed in the universal veil. As they expand, the caps later becoming bell-shaped or convex, and finally nearly flattened in age, attaining a diameter of 5–20 centimeters. The dry cap surface is covered with silky threads. Its color is white to yellowish, becoming more pale approaching the margin. The flesh is thin, soft, and white, and has an odor resembling raw potatoes. The gills are crowded close together, free from attachment to the stem.

Fruit bodies grow singly or in small groups on trunks and decayed stumps of dead hardwoods. It is often found in clefts and knotholes of dead or living tree trunks. It has been noted to fruit in the same location for several years. Despite its preference for hardwoods, it has been reported growing on rare instances on coniferous wood.

foragers delight

Foragers lucky enough to come across fresh silky rosegills are in for a treat! These mushrooms are a close relative of the paddy straw mushroom, Volvariella volvacea, a common ingredient in Asian dishes. Silky rosegill mushrooms have a mild, pleasant flavor, often described as radish-like, with a faint bean sprout smell. Some people find them to have a creaminess reminiscent of porcini mushrooms.
