Original Article


Dextrinoporus aquaticus gen. et sp. nov. is proposed based on ITS, nLSU, RPB2, and mtSSU genes molecular phylogeny and morphological characteristics from southwestern China. The new species is characterized by an annual, pileate basidiocarp with a poroid hymenophore, a monomitic hyphal system, thick-walled generative hyphae with dextrinoid and cyanophilous reactions, presence of dendrohyphidia and ellipsoid, thin-walled, and acyanophilous basidiospores. Phylogenetic analyses based on four gene sequences indicate that D. aquaticus belongs to Polyporaceae in which it has an isolated position, and the new taxon is related to the clade of Lopharia cinerascens and Dentocorticium sulphurellum.
