Cap: 0.5-2 cm diameter, conic to campanulate, yellow-brown to grey-brown, striate or with pleats over the margin; covered with minute glistening particles when young, but glabrous when mature. Flesh very soft, thin, pale buff.
Gills: adnate or free, distant, narrow, white when young, grey to black in age, not deliquescing to the same extent as other Coprinellus species.
Stem: 2-4 cm long, 0.1-0.2 cm thick, equal, curved, surface smooth to slightly scurfy, white, hollow.
Odor and taste: not distinctive.
Spore print: black.
Spores: elliptical, smooth, thick-walled, with an apical pore, nonamyloid, 7-10 x 4-6 µm.
Habitat: found growing gregariously in dense troops on well-rotted wood or buried wood, or at the base of standing dead trees. Fruiting in spring, summer and fall.
Edibility: edible (i.e., non-poisonous) but small and insubstantial.
Fruiting bodies are very fragile and likely to crumble on contact.
Extracts of the mycelial culture of Coprinellus disseminatus inhibits proliferation and induces apoptosis in human cervical carcinoma cells by activation of caspase, a key protein involved in the regulation of apoptosis (Han et al., 1999).
Polysaccharides extracted from the mycelial culture of C. disseminatus and administered intraperitoneally into white mice at a dosage of 300 mg/kg inhibited the growth of Sarcoma 180 and Ehrlich solid cancers by 100% and 90%, respectively (Ohtsuka et al., 1973).
The Truth About Medicinal Mushrooms
Medicinal Mushrooms are great. One of the few supplements I feel confident taking that actually has benefits. Most of the supplement industry is selling you on placebo, but I don't feel that's the case with medicinal mushrooms. HOWEVER; a large portion of the Mushroom Industry is corrupt. Come read this article if you want to find out the Dirty Secret in the Mushroom Industry and how to choose an Authentic Mushroom Supplement.
