Two New Species of Fibrodontia (Trechisporales, Basidiomycota) with a Key to Worldwide Species.

ABSTRACT: Fibrodontia is a genus of wood-inhabiting fungi consisting of four species so far, including F. gossypina as generic type. Two new species, Fibrodontia austrosinensis and F. subalba, are described and illustrated from China. Fibrodontia austrosinensis from southwestern China is characterized by a grandinioid to odontioid hymenophore with numerous small aculei, a dimitic hyphal system with scattered, smooth skeletal hyphae and ellipsoid basidiospores measuring 4.2-5.2 × 3.5-4.5 μm. Fibrodontia subalba from the West Tianshan Mountain in northwestern China is distinguished by an odontioid to hydnoid hymenophore, a dimitic hyphal system, and ellipsoid basidiospores measuring 3.7-4.4 × 2.8-3.4 μm. The phylogenies inferred from the data set of nuc rDNA ITS1-5.8S-ITS2 (ITS) and D1-D2 domains of n
