There have been abundant mycological expeditions to Patagonia, but locations sampled covered only a minimum portion of this extent region. In this way, most expeditions were focused in opposite endings of Subantarctic Forests: Tierra del Fuego at the south, and Neuquén and Rio Negro (Argentina), Santiago and Maule (Chile) at the north. All the territory comprehended between these provinces remains largely unknown for agaricoid fungi. The primal objective of the present work was to assess the richness of agaricoid species present in Nothofagus pumilio (lenga) forests in Chubut (Argentina), a part of this large portion of territory where no previous information is available. Four samplings took place from 2012 to 2014 in three different forests of Chubut province of Argentina. A total of 130 species of agaricoid fungi were found. Among them, 125 belong to Agaricales, 2 to Boletales and 3 to Russulales. Cortinariaceae (Agaricales) was the most diverse family, with 57 species. A key to all agaricoid species found is presented. We provide new records for 4 species at country level and 124 at province level.
