Albatrellus shouxiangu (Albatrellaceae, Russuales): a new terrestrial stipitate species from Eastern China

A new species, Albatrellus shouxiangu, is described from eastern China based on morphology and phylogenetic analysis using a combined dataset of ITS + nLSU + tef 1 -α + rpb 1 sequences. Albatrellus shouxiangu is characterized by annual, terrestrial, laterally stipitate basidiomata with saffron pileal surface when juvenile, sulphur-yellow to buff when mature, and white pores when fresh, generative hyphae with simple septa, subglobose, weakly amyloid basidiospores measuring 4.4–5.5 × 3.9–4.8 μm, and growing on ground in Vaccinium forests.

Phylogenetic analyses confirm its placement within the genus Albatrellus, forming a distinct lineage closely related to A. cantharellus. The present study enhances the understanding of the diversity of Albatrellus in China.
