I’ve found several in the past, and usually they are not mature, so Dr. Trappe sent back identification as merely Radiigera sps. Nice to know genus can be identified by felty peridium.

Fred agrees. Made the change.

The genus Radiigera has been misinterpreted by many since Zeller described it in 1944. It was straightened out in 1996 when Radiigera atrogleba was transferred to Pyrenogaster by Dominguez de Toledo & Castellano leaving four species in Radiigera. They examined all of the herbaria records they could find and reported that Pyrenogaster atrogleba fruits in California only at higher elevations and is recorded from Placer, Plumas, Sierra and Trinity Counties.
Of the four remaining species in Radiigera, R. bushnellii is known only from a couple of rare collections in Oregon, R. flexuosa is known only from Sweden and the remaining two species are both West Coast species known from Mexico to Washington. R. taylorii is commonly found in Humboldt Co. and has a smooth peridium. R. fuscogleba is common in most of the coastal counties in CA and has a felty peridium that usually has debris adhering to it. Looking at the macrocharacters, your photos appear to be closest to Radiigera fuscogleba.
