E-Flora BC: Electronic Atlas of the Flora of British Columbia

Summary:
Thelephora mollissima either 1) lies flat on the substrate, with the smooth fuscous-purple spore-bearing surface showing, the edge bent outward to form shingled shelf-like caps, or 2) has a nearly central stem. The cap color is whitish becoming brownish with the cap surface subtomentose. The description is derived from Corner based on the Friesian interpretation of 1874.

It has been identified by Jim Ginns from western Vancouver Island in BC (pers. comm.), using the concepts of Stalpers. It is also found in Europe.

Fruiting body:
