Pseudoclitocybe cyathiformis
Mycologia 48: 725. 1956.
Common Name: none
Synonym: Clitocybe cyathiformis (Bull.) Kummer; Cantharellula cyathiformis (Bull.) Singer
For description see Bigelow, Siegel & Schwarz, & 'California Mushrooms'.
Solitary to scattered in wood-rich soil or on hardwood or conifer logs; fruiting in late fall to winter, widely distributed.
Not recommended.
Pseudoclitocybe cyathiformis can be distinguished by dark brown to grayish brown cap and stipe, greyish to pale greyish white, sometimes forked gills, and habit in humus or on decayed wood. It was moved from Clitocybe into its own genus because of amyloid spores and lack of clamp connections. Several similar species occur in California. Arrhenia epichysium is smaller, always grows on wood, and has a distinctively translucent-striate cap. Clitocybe trullaeformis has a dark brown, finely velvety cap with a margin that fades to grayish orange, yellowish white gills, smaller inamyloid spores, and clamped hyphae. Clitocybula atrialba has a dark brown cap but white gills, a paler furfuraceous to scabrous stipe, amyloid subglobose spores, and clamped hyphae.
