Recognized by sight: Small basidiocarps, Pale colored context. Not entirely certain if sessiliforme is a valid taxon though. Specimens are smaller and have a lighter context than G.sessile.
Used references: The Polyporaceae of Mexico, W.A Murril (1907),Torres-Torres, M.G.; Guzmán-Dávalos,L.; Mello Gugliotta de, A.. 2012. Ganoderma in Brazil: known species and new records. Mycotaxon. 121:93-132,Ganoderma sessiliforme Murrill, Bull. N.Y.
Bot. Garden 8:149.1912.
Based on microscopic features: Hyphal system trimitic,Spores are 8.5 µm x 5.9 µm fairly smaller than G.sessile, though they had to be extracted from the pore tubes so may have aprox. 1 µm margin of error due to immaturity. Size is slightly larger than that recorded for the holotype of G.sessiliforme.

i’d say Ganoderma tsugae “group.”
however, im not into SPECULATING about such nonsense, without any REAL evidence.

I’ve not seen a Ganoderma with such a wrinkled cap. Specific suggestions?
