Abstract

<br> In this study, two new species,<br> Leucoagaricus bailangshanensis<br> and<br> Leucocoprinus ferrugineus<br> , were discovered. Phylogenetic analyses based on ITS, nrLSU,<br> rpb<br> 2, and<br> tef<br> 1-<br> α<br> sequences confirm that these taxa represent distinct lineages within well-supported monophyletic groups.<br> Leucoagaricus bailangshanensis<br> 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.<br> Leucocoprinus ferrugineus<br> 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.<br>
