title: Molecular phylogeny and morphology reveal a new species of Amyloporia (Basidiomycota) from China.
abstract: Amyloporia pinea sp. nov. is described and illustrated on the basis of collections from southern China. Morphology and phylogenetic analysis of rDNA ITS sequences support this new species. Morphologically, it is characterized by resupinate, annual basidiocarps, cream to yellowish buff pore surface when fresh, which becomes yellowish brown to clay-buff upon drying, a dimitic hyphal system with clamped generative hyphae and inamyloid skeletal hyphae, fusoid cystidioles, and cylindrical basidiospores; moreover, it causes a brown rot. Molecular phylogeny inferred from ITS sequence data suggested a close relationship between A. pinea and Amyloporia crassa sensu lato. Antrodia subxantha has amyloid skeletal hyphae, and grouped within the Amyloporia clade, hence, it is transferred to Amyloporia, and a new combination Amyloporia subxantha is proposed.
