title: Two new species of Fomitiporia (Hymenochaetales, Basidiomycota) from Tibet, southwest China.
abstract: Two new species of Fomitiporia growing on Hippophae trees, F. norbulingka and F. subhippophaëicola, are described from southwest China based on morphological characters and phylogenetic analysis. Fomitiporia norbulingka is characterized by pileate basidiomata, mostly angular pores (6-9 per mm), slightly thick-walled generative hyphae, subglobose to globose basidiospores (6.5-7 × 5.5-7 μm), and absence of cystidioles. Fomitiporia subhippophaëicola is diagnostic by effused-reflexed to pileate basidiomata, angular pores (8-10 per mm), thick-walled generative hyphae, subglobose to obovoid basidiospores (6-8 × 5.5-7 μm), and presence of ventricose to fusoid cystidioles. Phylogenetic analysis inferred from combined sequences including the nuc rDNA ITS1-5.8-ITS2 region, 28S rDNA D1-D2 domains, partial sequences of translation elongation factor 1-α, and RNA polymerase II second largest subunits genes indicated that F. norbulingka and F. subhippophaëicola represent two new lineages which group together with F. hippophaëicola.
