Abstract

In this study, two new species, Leucoagaricus bailangshanensis and Leucocoprinus ferrugineus , were discovered. Phylogenetic analyses based on ITS, nrLSU, rpb 2, and tef 1- α sequences confirm that these taxa represent distinct lineages within well-supported monophyletic groups. Leucoagaricus bailangshanensis is characterized by a yellow-orange center on the pileus, a margin bearing floccules, and relatively long sterigmata, which distinguish it from closely related species. Leucocoprinus ferrugineus can be recognized by its mahogany-red pileus center, a white annulus with a tomato-red margin that turns brown when bruised, and ellipsoid basidiospores. Detailed morphological descriptions, along with color photographs, illustrations, and a phylogenetic tree, are provided to clarify the taxonomic positions and relationships of these two new species.
