I tried keying these in:
Domínquez de Toledo, L.S. & Castellano, M.A. (1996). A Revision of the Genera Radiigera and Pyrenogaster. Mycologia 88(5): 863-884.
No attractive matches.
All the photos are from the same patch, but over a month apart. These mature very slowly and change color dramatically when exposed to sun and wind. They begin reddish-brown with orangey blotches, and fade to dull beige/tan or greenish from algal growth. Undersides of mature, exposed specimens retain the original color.
Texture very smooth when young, becoming slightly and finely granular-scaly in age.
Growing in mulched, rootbound soil under redwood, with one Douglas-Fir nearby.
Clamps present in the hyphae of the fertile inner surface.
Sliced peridium and spore mass white with faint pinkish tinges when young, spore mass becoming dark brownish-black.
Spores 5 × 5 microns, globose, verrucose, brown in KOH
Large, contorted elements on outer surface.
Microscopic transect of peridium, outer surface to left, next layer golden in KOH, followed by horizontally arranged hyphae, and pseudoparenchymatic inner layer (nearest to spore mass).
Spore mass with sparsely septate, somewhat irregularly inflated hyphae with clamps (very difficult to see in this photo)
