This taxon falls within the family Omphalotaceae as a sister group to Gymnopus in phylogenetic analyses based on nuclear ribosomal DNA from the internal transcribed spacer region and 5? end of the large subunit. Morphologically, it is characterized by convex to flabellate fruiting bodies with distinctly gelatinized trama, pileipellis in the form of a cutis with erect fascicles of tubular, spirally-incrusted hyphae, and nonamyloid, broadly ellipsoid basidiospores. This combination of features, in particular the lack of a rameales structure, serve to distinguish Gymnopanella from Gymnopus, Marasmiellus, and other similar genera of the Omphalotaceae or Marasmiaceae. The new taxon is known only from Chilean Nothofagus forests of approximately 45-46 ? South latitude, but concerted searching in similar habitats in surrounding areas or in New Zealand may extend the known range considerably.} }
