摘要: The genus Laccaria (Hydnangiaceae, Agaricales) is an important ectomycorrhizal symbiont of a broad range of host plants. Laccaria guizhouensis was collected from a subtropical mixed forest dominated by Fagaceae in Southwest China and described based on morphological characteristics and molecular data. Laccaria guizhouensis is characterised by its medium-sized basidiocarps and strong striate or sulcatus, flesh-coloured to brown pileus, flesh-coloured to brown lamellae, 2- to 4-spored basidia, globose to obellipsoid, hyaline, moderately echinulate basidiospores, and 1-1.5 mu m-long echinulate. Phylogenetic analyses based on ITS sequences (HMAS352265 and HMAS352266) indicated that L. guizhouensis represented a new species separated from all other Laccaria species.
