Abstract The diversity of Corticiaceae found in the
Patagonian Andes forests of southern Argentina was studied. A total of 168
species of Corticiaceae sens. lat. are recorded. The total diversity of corticioid
fungi is estimated to be 250-290 species based on the accumulated increase
of taxon diversity on different substrates. Most recorded species (56%) are
cosmopolitan or widely distributed, 20% endemic, 4% austral, 17% amphitropical,
and 3% show other distributions. The genera Dendrothele and Hyphodontia
contain a high number of endemic species. Taxa that are particularly interesting
due to their morphological peculiarities and/or their possible phylogenetic
relationships are discussed. On the basis of 110 species recorded from Tierra
del Fuego, we estimated that about half of these species are very rare and
highly vulnerable in that island.
