A novel, lignicolous agaric from Nothofagus forests of southern Chile is described as a new genus and species, Gymnopanella nothofagi This taxon falls within the family Omphalotaceae as a sister group to Gymnopus in phylogenetic analyses based on sequences spanning the internal transcribed spacer region and D1/D2 region of nuclear 28S rDNA. Morphologically it is characterized by convex to flabellate basidiomata with distinctly gelatinized trama, pileipellis in the form of a cutis with erect fascicles of cylindrical, 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 at approximately 45-46° south latitude, but concerted searching in similar habitats in surrounding areas or in New Zealand may extend the known range considerably.
