Five new wood-inhabiting fungi, , , , , and , are proposed based on a combination of morphological features and molecular evidence. is characterized by brittle basidiomata, pruinose hymenophore with a white hymenial surface, a monomitic hyphal system with clamped generative hyphae, and ellipsoid basidiospores. is characterized by a grandinioid hymenial surface, the presence of capitate cystidia, and ellipsoid basidiospores. is characterized by an odontioid hymenial surface, a monomitic hyphal system with clamped generative hyphae, and broad ellipsoid-to-subglobose basidiospores. is characterized by a cracking basidiomata with a grandinioid hymenial surface, and ellipsoid basidiospores. is characterized by a poroid hymenophore with an angular or slightly daedaleoid configuration, and ellipsoid-to-broad-ellipsoid basidiospores. Sequences of ITS and nLSU rRNA markers of the studied samples were generated and phylogenetic analyses were performed with the maximum likelihood, maximum parsimony, and Bayesian inference methods. The phylogram based on the ITS+nLSU rDNA gene regions (Fig. 1) included six genera within the families Chaetoporellaceae, Hyphodontiaceae, Hymenochaetaceae, and Schizoporaceae (Hymenochaetales)- , , , , , and -in which the five new species were grouped into genera and . The phylogenetic tree inferred from the ITS sequences highlighted that formed a monophyletic lineage and was then grouped closely with , , and ; additionally, was sister to with strong supports. The topology, based on the ITS sequences, revealed that was retrieved as a sister to ; was grouped with the four taxa , , , and ; and was clustered with , , , , and .
