Abstract

A new species and a new record of Fuscoporia species were discovered in the Xizang Autonomous Region, China, through integrated morphological and molecular phylogenetic analyses. The new species, described as Fuscoporia medogensis, was characterized by annual, resupinate basidiomata, sinuous pores (7–9 per mm), and cylindrical basidiospores measuring 4.5–5.5 × 1.5–2.0 μm. The new record, identified as Fuscoporia viticola, was determined based on five specimens collected on Pinus yunnanensis. Phylogenetic analyses of combined ITS and nLSU rDNA sequences strongly support the distinct status of these taxa within the genus Fuscoporia. Our study contributes to the taxonomy of Fuscoporia by raising the number of known Chinese species to 29 and providing a diagnostic key, thereby enhancing knowledge of fungal diversity in high-altitude ecosystems.
