What You Should Know
Coltricia cinnamomea is a species of Fungi in the family Hymenochaetaceae. This vase-shaped polypore occurs commonly in the San Francisco Bay area under Monterey pines (Pinus radiatus). It is recognized by rusty-brown, often clustered fruiting bodies. The caps are usually faintly-zoned cap with appressed fibrils, in certain light sometimes appear to glisten. Coltricia perennis, found in the Sierra Nevada and elsewhere, differs in having a more distinctly-zoned cap, and a matted-tomentose surface.
Dried mushrooms of the Coltricia cinnamomea can be used as a natural fiber dye that gives brown-beige color.
Other names: Fairy Stool, Shiny Cinnamon Polypore.

Coltricia cinnamomea Medicinal Properties
Antitumor effects. Polysaccharides extracted from the mycelial culture of C. cinnamomea and administered intraperitoneally into white mice at a dosage of 300 mg/kg inhibited the growth of Sarcoma 180 and Ehrlich solid cancers by 90% and 100%, respectively (Ohtsuka et al., 1973).
