Common name

Wood woollyfoot

Description

Cap: 2.5-6 cm diameter, convex to plane, often with broad umbo and irregularly lobed margins; glabrous; sometimes grooved above gills; yellow-brown to pink-brown with paler margin; hygrophanous; context white to pale yellow.
Stem: 3-7.5 cm long and 0.3-0.8 cm thick; smooth or floccose at apex becoming fibrillose-striate below, usually expanded towards base; ochre-brown to yellowish, often more orange-brown towards the base which is covered with buff to yellowish hairs.
Gills: free, distant, sometimes forked near stem; pale or yellowish changing to brownish; edges entire or finely whitish granulose fringed.

Spores: 8.5-10 x 3-4 µm, smooth, elliptic to subcylindrical.
Odor: mild.
Taste: peppery to pungent/acrid.
Edibility: considered too acrid to eat. Furthermore, reports of the presence of the toxic compound hydrocyanic acid (Bach, 1948) indicate consumption be avoided.
Habitat: usually found in dense groups in forest litter, on conifer and hardwood debris.

Bioactive compounds

Two 3-indolinone dimers have been isolated from EtOAc extracts of the fruit bodies of Collybia peronata, peronatins A and B (shown below). The diastereoisomeric compounds are formed in the fruit bodies upon injury, from enzymatic hydrolysis of an indole precursor and oxidative coupling of the derived indoxyl radicals (Pang and Sterner, 1994). Further work on the synthesis and isomerization of these indole-compounds has been reported (Stachel et al., 1997).

Medicinal properties
Antitumor effects

Antibacterial activity

Reporting on the favorable influence of sodium citrate on the production of antibiotics in Marasmius spp (Öblom, 1950), it is suggested that this species has antibacterial activity: "Recent work on antibiotics has shown that Marasmius urens (Bull). Fr. is highly active against several pathogenic bacteria (Öblom and Wallmark, unpublished)." This work (i.e., the effect of organic acids on antibiotic production) was later elaborated and expanded (Öblom, 1951), and Staphylococcus aureus was used as the test bacteria.

Antitumor effects

An extract of the fruit bodies inhibited the growth of Sarcoma 180 and Ehrlich solid cancers in mice by 60% (Ohtsuka et al., 1973).

Description

Cap: 2-4 cm diameter, oval to campanulate, later expanding to broadly convex, margin upturned in age; color variable from tawny brown, reddish brown, to ochre brown, fading with age and becoming grayish near the margin; hygrophanous; surface striate, initially covered with glistening particles that easily wash or wear off; margin prominently lined nearly to the center; flesh thin fragile, pale brown.
Gills: adnexed or free, close, white when young, then purplish-brown to black, eventually deliquescing; 3-8 mm broad.
The gills of the medicinal mushroom Coprinellus micaceus
  Credit: Robert Sasata, © healing-mushrooms.net
Stem: 3-10 cm x 2-6 mm, white, pruinose, equal or with base clavate or bulbous, often with a volva-like margin; hollow, fragile
Spores: 6.5-10.0 x 4.5-7.0 x 4.5-5.5 µm, ellipsoid or ovoid with conical base (mitriform) and truncate apex, brown.
Spore print: black.
Taste: mild, pleasant.
Edibility: edible before the gills deliquesce.
Habitat: fasciculate or gregarious around dead trunks or stumps, on lawns and along sidewalks and streets; saprobic; spring-fall; common. Stewart (1926) claims to have gathered 38 pounds from a single large elm stump in one season (between May 1 and October 1, combining 8-10 successive crops).

An old reference (Stewart, 1926) mentions that autodigestion results in 72-74% of the weight of the caps transforming into liquid. This liquid, when pure, is light reddish brown, but usually appears black, due to the admixture of spores and particles of undigested residue. Another ancient report (Pady, 1941) mentions that 5-7 days are required for the mushroom to reach maturity - at least when growing in the crack of a hardwood floor!

Bioactive compounds

Two novel compounds have been isolated from the methanolic extract of C. micaceus,  micaceol (a sterol), and (Z,Z)-4-oxo-2,5-heptadienedioic acid. The latter compound, present at a concentration of 32 µg/mL, inhibited the enzyme glutathione S-transferase (GST) by 26.8% (Zahid et al., 2006). GST has been implicated in the resistance of cancer cells against chemotherapeutic agents, and GST inhibitors have the potential to be used as adjuvants in cancer chemotherapy.

Medicinal properties
Antitumor effects

An extract of the fruit bodies of the mica cap inhibited the growth of Sarcoma 180 and Ehrlich solid cancers in mice by 70% and 80%, respectively (Ohtsuka et al., 1973).

Antioxidant

The antioxidant activity of cultured liquid, mycelial extract and biomass suspension from cultures of C. micaceus have been shown to have antioxidative potential to inhibit the reaction of free-radical peroxide oxidation of lipids in rat brain homogenate (Badalyan, 2003).

Antimicrobial

The antimicrobial activity of various species of the genus Coprinus, including 2 strains of C. micaceus (VKM F-2945 and VKM F-2946) were evaluated against Bacillus subtilis AONN 6633, B. mycoides 537, B. pumilis NCTC 8241, Leuconostoc mesenteroides VKPM B-4177, Micrococcus luteus NCTC 8340, Staphylococcus aureus FDA 209P, INA 00761, INA 00762, Escherichia coli ATCC 25922, Comamonas terrigena ATCC 8461, Pseudomonas aeruginosa ATCC 27853, Aspergillus niger INA 00760, Saccharomyces cerevisiae RIA 259, and Candida albicans INA 00763 (Efremenkova 2003).

The compound micaceol (described above) has demonstrated modest anti-bacterial activity against Corynebacterium xerosis and Staphylococcus aureus, with minimal inhibitory concentration (MIC) values of 82.35 and 146 µg/mL, respectively (Zahid et al., 2006).
