Abstract
Marasmius is a large and important genus in the forest, with potential research and application value, while its diversity in China remains under-documented. In this work, three new species of Marasmius belonging to subgen. Globulares were studied from southwestern China. Morphologically, Marasmius flavosulcatus is characterized by the lemon-yellow, plicated pileus and large basidiospores. Marasmius griseobrunneus is characterized by a white to grayish brown, faintly striate pileus, a stipe tapering towards the base, subdistant lamellae, medium-sized basidiospores (7.06 × 3.91 μm), and clavate caulocystidia. Marasmius variegatus is characterized by a yellowish, spotted pileus and dimorphic cells in both the cheilocystidia and the pileipellis. Based on ITS and LSU phylogenetic analyses, the three species belong to the purpureostriatus, wynneae and luteoli series, respectively. In this study, descriptions, photographs of the basidiomata, line drawings, phylogenetic analysis results and comparisons with related species are provided.
