Fomitiporia chilensis and Phylloporia boldo are described as new poroid species in the Hymenochaetaceae based on morphological, cultural, ecological and phylogenetic analyses. Fomitiporia chilensis pertains to the F. punctata species complex, being related to its Neotropical taxa. It is distinguished by pulvinate to effused basidiomes that develop an indurated margin, by contextual tissue between the tube strata, basidiospores larger than 6.0 µm, and by growing on dead tissues of P. boldus and Cryptocarya alba. Its closest phylogenetic relatives are F. neotropica and F. impercepta, which differ by flatter basidiomes and by microscopical features. Phylloporia boldo grows and sporulates exclusively on living Peumus boldus. It is distinguished by a pileate basidiome with sulcate, indurated pileal surface, a dimitic hyphal system and by relatively large basidiospores 5.4‒6.0 × 4.4‒5.0 µm with dull chestnut walls. It was found to be phylogenetically related to Ph. dependens, described from China, both species being distantly related to other species in Phylloporia.
