Recognized by sight: According to Jean Lodge, Laura Guzman told her that Pegler had described this large, brightly colored Gymnopilus from South America which should have been G. spectabilis, but he mistakenly swapped the name with G. imperialis. This is likely the same mushroom. My understanding is that this is in fact Gymnopilus spectabilis subsp. pampeanus which would be the deprecated synonym for Pseudogymnopilus pampeanus.

but at the expense of accuracy. Some relevant papers are “Traditional infrageneric classification of Gymnopilus is not supported by ribosomal DNA sequence data” (Guzman-Davalos 2003), “The genus Gymnopilus (Fungi, Agaricales) in the Czech Republic” (Holec 2005), and “Species of Gymnopilus P. Karst: New to India” (Kaur et al 2015).

(A study does not need to focus on neotropical species to draw a valid taxonomic conclusion about a species that occurs in the neotropics.)

All validly published names exist forever, but Pseudogymnopilus now only exists as a less correct synonym of Gymnopilus.

It is a very striking mushroom, so I thought it would be easy to ID. I use Index Fungorum as my taxonomy bible, which lists it as Pseudogymnopilus which as far as I know is a monotypic genus. Does that mean it no longer exists? What are the recent treatments and are you sure they are treatments of Neotropical spectabilis?

This taxon is in Gymnopilus

All recent treatments of the genus have it as “Gymnopilus pampeanus”, “Gymnopilus spectabilis subsp. pampeanus”, or simply a synonym of G. spectabilis. It’s not clear which is the best name, so the middle choice is the safest bet on all counts.
