Phellinus piptadeniae (Hymenochaetaceae,Hymenochaetales) as currently accepted is characterizedby having applanate to ungulate basidiome with the pilearsurface concentrically sulcate, radially cracked in oldspecimens, and a sinuous black line in the context. Thespecies has been recorded in seasonally dry forests ofdifferent Brazilian domains, often associated with legumehosts. It occurs highly specifically associated with Piptadeniagonoacantha in semideciduous forest of the AtlanticForest domain in southeastern Brazil. In the Caatingadry woodlands, northeastern Brazil, Phellinus piptadeniaeoccurs as host recurrent of different Piptadenia species.During recent polypore surveys, specimens that are morphologicallysimilar to the type were collected in seasonallydry tropical forests (SDTFs) of northwestern Peru alsoon legume hosts (Libidibia glabrata and Pithecellobiumexcelsum). In this paper, we discuss the morphologicalvariation, host range, and distribution of Phellinus piptadeniaein the context of the historical biogeography ofthe neotropical SDTF biome. Some taxonomic implicationsthat should be further investigated in a molecular phylogeneticframework are also addressed.
