thinner and more adnate [more tightly attached] than Piloderma fallax; olivaceous - olive-brown; "often with small drop-craters" in the spore-bearing surface; otherwise like Piloderma croceum (Eriksson), olive brown hymenial surface when dry, but in other features like Piloderma fallax, (Ginns(23))
