Studies in Ganodermataceae (Basidiomycota) : the concept of Ganoderma coffeatum in the Neotropics and East Asia

The circumscription of Ganoderma coffeatum has been revised, based on morphological data. It is evidenced that the commonly used concept of the species encompassed several taxa. In addition to G. coffeatum s.s., two additional species occur endemically in the Neotropics and are identified as Ganoderma flaviporum and Amauroderma deviatum. In tropical Asia, two other taxa were evidenced but are so far of uncertain status. The main features of G. coffeatum, G. flaviporum, and A. deviatum are emphasized. A preliminary key to the Ganodermataceae with a complex endosporic ornamentation pattern is presented.
