Furtadomyces nom. nov. (Ganodermataceae, Basidiomycota) with description of F. sumptuosus, a new species of ganodermatoid fungi from Brazil

Based on morphological and phylogenetic evidence, a new species of ganodermatoid fungi is recorded and described from the Brazilian Cerrado. After the species was placed in Furtadoa, this genus name was declared an illegitimate homonym by the Index Fungorum and MycoBank databases, according to Art. 53.1 of the International Code of Nomenclature for algae, fungi, and plants, thus requiring the need to replace Furtadoa. Therefore, Furtadomyces is proposed as the new name for the genus. The new species Furtadomyces sumptuosus is characterized by the combination of large basidiomata, multiple pilei, presence of radial striae on the pilear surface, an involute margin exposing the pore surface, and large, subglobose to ellipsoid (7.2–) 9.1–11.2 (–13.3) × (6.6–) 7.1–8.8 (–10.4) μm, double-walled basidiospores. It is closely related to Furtadoa biseptata, evidenced morphologically by the presence of two different septa in the generative hyphae of the context. Phylogeny, morphological description, illustrations, and comments for F. sumptuosus are presented, as well as two new combinations in Furtadomyces: F. biseptatus and F. brasiliensis.
