Inonotus amazonicus sp. nov., I. calcitratus comb. nov. and notes on Phylloporia (Hymenochaetaceae, Agaricomycetes) from the Brazilian Amazonia

Abstract Inonotus amazonicus is described and illustrated as a new species based on specimens collected in Aripuana, in the state of Mato Grosso, Brazil, and deposited in herbarium INPA 34 years ago. This species is mainly distinguished from the others in the genus by the abundant, huge tramal setae and the duplex context covered by a persistent adpressed dark brown tomentum. Besides the description of the new species, one new combination is proposed: I. calcitratus, I. luteoumbrinus and Phylloporia spathulata are reported as new to the state of Roraima, P. chrysita to the state of Amazonas and P. pectinata to the state of Rondonia. Description and illustration of the new species and keys to the species of Inonotus and Phylloporia known to Brazil are provided.
