Mythicomyces corneipes
Mycotaxon 118: 456. 2011.
Common Name: none
Synonym: Psilocybe corneipes (Fr.) Sacc.
For descriptions see Castellano et al. & Siegel et al.
Solitary to gregarious, along margins of bogs among mosses or on wet soil under conifers and alder (Alnus spp.). Widespread but rare.
Unknown.
Mythicomyces corneipes can be distinguished by its orange-brown, hygrophanous cap, cartilaginous stipe that darkens from the base up, pale purple-brown spores, and amyloid incrustations on the cystidia. Stagnicola perplexa is very similar but it has smooth inamyloid spores not ornamented dextrinoid spores, is usually slightly paler, and has a discernibly bitter taste.
