Aged alder bracket (𝘐𝘯𝘰𝘯𝘰𝘵𝘶𝘴 𝘳𝘢𝘥𝘪𝘢𝘵𝘶𝘴 or 𝘔𝘦𝘯𝘴𝘶𝘭𝘢𝘳𝘪𝘢 𝘳𝘢𝘥𝘪𝘢𝘵𝘢), from the Wiley Trails.

I took the picture from an angle as if the tree were still standing, but the rotted out trunk had broken in the wind and lay horizontally across our path.

Numerous dark brown to black shelves of fungi adorn a gray tree trunk.

Clathrus baumii

Ecology: Saprobic; growing alone or gregariously in grassy areas; January; possibly widespread across Africa (see discussion above). The illustrated and described collection is from South Africa.

Mature Fruiting Body: 8 cm high; 7 cm wide; consisting of a round-ish, hollow lattice that arises from a stemlike structure.

Lattice Arms: About 1 cm wide and 3 mm thick; forming about 20 more or less round holes; edges of holes tightly striate for 2-4 mm; outer surfaces white, flattened, minutely pitted and spongelike; hollow; inner surfaces bumpy and dull yellowish; glebifers found on the inner surfaces at the intersections of the arms, 0.5-1.5 cm across, wart-like, bumpy.

Pseudostem: Poorly defined; about 2 cm high, whitish to dull yellowish, enclosed in a whitish volva.

Volva: Sac-like, encasing the base of the fruiting body; whitish.

Spore Slime: Dark brown; covering the glebifers; very malodorous.

Microscopic Features: Spores 3.5-5 x 1.5-2 m; subcylindric; smooth; hyaline in KOH, often with two small guttules. Sphaerocysts of the pseudostipe 12-24 m; subglobose; walls about 0.5 m thick; hyaline in KOH. Hyphae of the volva 1-3 m wide; smooth; thin-walled; hyaline in KOH; septate; clamp connections not found.

Hericium coralloides

mushroomexpert.com/Hericium_co

Ecology: Saprobic and possibly parasitic; growing alone or gregariously on fallen hardwood branches and stumps; late summer and fall, or over winter and in spring in warmer climates; apparently widely distributed in North America. The illustrated and described collections are from Illinois, Michigan, and Minnesota.

Fruiting Body: 8-20 cm across; consisting of branches arising from a more or less central core that is attached to the wood; branches 0.5-1 cm thick, smooth, adorned with fleshy spines; spines 0.5-1 cm long, up to 1 mm wide, white when fresh, becoming faintly yellowish to brownish in old age.

Flesh: White; not changing when sliced.

Odor and Taste: Not distinctive.

Spore Print: White.

Microscopic Features: Spores 3-4 x 2.5-3.5 m; globose; smooth or minutely roughened; hyaline and uniguttulate in KOH; amyloid. Basidia 16-20 x 3-4 m; subclavate; 4-sterigmate. Gloeoplerous hyphae present, sometimes extending into hymenium to become cystidia (up to 40 x 5 m, cylindric with knobbed apices, smooth, thin-walled).

Lactarius piperatus

mushroomexpert.com/Lactarius_p

Ecology: Mycorrhizal with oaks and other hardwoods; growing scattered, gregariously, or sometimes in dense troops; summer; apparently widely distributed east of the Rocky Mountains.

Cap: 4-15 cm; broadly convex, becoming flat, shallowly depressed, or vase-shaped; dry; the margin even; bald; white or whitish, sometimes discoloring a little yellowish or brownish with age.

Gills: Attached to the stem or running slightly down it; very crowded; forking frequently; white becoming pale cream.

Stem: 2-8 cm long; 1-2.5 cm thick; white; more or less equal, or tapering a little to base; bald; without potholes; solid.

Flesh: White; thick; hard; sometimes discoloring yellowish with age.

Milk: Copious; white; unchanging after exposure, or changing slowly to yellowish; not staining tissues, or staining them slightly yellowish; not staining white paper.

Odor and Taste: Odor not distinctive; taste excruciatingly acrid.

Chemical Reactions: KOH pale magenta on cap surface.

Spore Print: White.

Microscopic Features: Spores 5-10 x 5-8 ; broadly ellipsoid; ornamentation less than 0.5 high, as scattered warts and lines that occasionally form vague patterns but do not form reticula. Pleuromacrocystidia up to about 70 long; subcylindric. Cheilocystidia similar. Pileipellis a hyphoepithelium with the upper, cutis-like layer very thin and the lower, cellular layer easily demonstrated.

Lactarius badiosanguineus

mushroomexpert.com/Lactarius_b

Ecology: Mycorrhizal with spruces, firs, and perhaps other conifers; summer and fall; in North America reported from Newfoundland (Malloch, 2010) and, here, from Colorado.

Cap: 2-8.5 cm; broadly convex with an inrolled margin when young; becoming flat, shallowly depressed or shallowly vase-shaped; greasy to dry; shiny; bald; deep brownish red to reddish brown; evenly colored to the margin; without zones of color.

Gills: Attached to the stem or beginning to run down it; close or crowded; pale orange or yellowish, becoming dull cinnamon with age; not bruising.

Stem: 3-9 cm long; up to 1.5 cm thick; more or less equal; dry; without potholes; colored like the cap, but paler.

Flesh: Whitish to pinkish; not changing when sliced.

Milk: White; unchanging; not staining white paper yellow.

Odor and Taste: Odor not distinctive; taste mild or slowly, slightly acrid.

Spore Print: Cream.

Chemical Reactions: KOH negative on cap surface.

Dried Specimens: Dried caps and stems are dark brown, without any trace of red; gills are dull orange.

Microscopic Features: Spores 7-9 x 5.5-7 ; broadly ellipsoid; ornamentation 0.5-1 high, as amyloid warts and connecting lines that form distinct stripes and subreticulate patterns. Pleuromacrocystidia abundant and prominent; subcylindric to subfusiform; to about 100 x 10 . Cheilocystidia scattered and inconspicuous; subcylindric to subfusiform; to about 40 long. Pileipellis an oedotrichoderm, slightly gelatinized.

Hypomyces cervinigenus

mushroomexpert.com/Hypomyces_c

Ecology: Parasitic on various species of Helvella; summer and fall, or over winter in warm climates; originally described from Washington; widely distributed in North America; occasionally reported from Europe (perhaps inaccurately). The illustrated and described collections are from California and Illinois.

Fruiting Body: A powdery, mold-like covering that is at first whitish and then becomes pinkish to pink, and eventually pale brownish.

Chemical Reactions: KOH on surface negative.

Microscopic Features: Aleuriospores 10-15 m including ornamentation; globose; echinate with spines 1-1.5 m long; hyaline to dull golden in KOH. Subicular hyphae 2-5 m wide, septate, smooth, hyaline in KOH.
