for P. amazonicus, and probably not a Phaeolus in the opinion of Drs. Elisandro Ricardo Drechsler Santos and Gerardo L. Robledo. It resembles a palm-parasitic Coltricia known from Brazil, Argentina and Bolivia, seen and discussed in Observation 177766

at the base of another Motacu palm, both in mature and immature states. Same pore surface bruising, same golden brown, concentrically ringed, shiny context tissue, same velutinous to scruffy pileus surface. this observation was never subjected to KOH spot testing, but the new material is xanthochroic on all tissues, as I strongly suspect this one would have been as well if tested.

the observations are from opposite ends of the country, but are associated with the same species of palm at practically the same elevations. with due acknowledgment of the possibility that this may belong to an obscure, (Neo)tropics-specific genus which just happens to look like Phaeolus to northern temperate eyes, I would still put money on Phaeolus.

currently awaiting a copy of this paper:

De Jesus, M.A.; Ryvarden, L. 2010. Studies in neotropical polypores 28. Two new species from Amazonas, Brazil. Synopsis Fungorum. 27:73-77

in which P. amazonicus is described from Brazilian rain forest. Will also solicit the in-person opinion of Gerardo Robledo in the coming weeks.
