Mushrooms of Hawaii (Desjardin, Hemmes) describes Pyrrhoglossum pyrrhum as follows:


Pyrrhoglossum pyrrhum (Berk. & M. A. Curtis) Singer

Cap 5-15 mm broad, convex to fan shaped, margin wavy, nonstriate, surface suedelike to glabrous, pale brownish orange; odor strong and pleasant, taste very bitter. Gills adnexed, close to crowded, narrow, deep brownish orange. Stem rudimentary, lateral, 1-25 × 1 mm, minutely pubescent, brownish orange, arising from copious coarse white rhizomorphs. Spore deposit rusty brown. Edibility: unknown.

Pyrrhoglossum pyrrhum is a rare species in the Hawaiian Islands, known at present from a single population on the Kaluapuhi Trail at Koke’e State Park of Kaua’i. The fan-shaped caps with deep rusty brown gills and a rudimentary lateral stem, which arises from coarse white rhizomorphs, are diagnostic features. It grows on very rotten logs of native ohi’a trees. Is: KA.


Though not P. pyrrhum, this collection bears sufficient resemblance to its rare Hawaiian cousin to warrant the proposal that they may share the same genus.
