Tomentellopsis rosannae sp. nov. (Basidiomycota, Thelephorales), first species in the genus described from the Southern Hemisphere.

Patagonian collections of the corticioid genus Tomentellopsis have been treated in the past as T. echinospora, a common northern hemisphere species. New collections with DNA sequence data are distinct from the northern hemisphere taxon and must be considered a different species, endemic to the temperate subantarctic forests of Patagonia. We use molecular and morphological methodologies to study this new corticioid fungus and describe it as Tomentellopsis rosannae sp. nov.
