摘要： A new species of Cuphophyllus (Hygrophoraceae, Agaricales) was discovered in mixed coniferous and broad-leaved forests (Pinaceae and Fagaceae) and grassland margins in Lijiang, North-west Yunnan, and South-west China. The species is described using morphological and molecular methods. Based on on-site habitat observation data and a literature review, the novel species is best described as a saprobic macrofungus that thrives in soil humus within mixed pine forests or grasslands. The basidiomata of the novel species exhibit macroscopic similarities to C. virgineus; however, C. lijiangensis sp. nov. differs primarily in having a smaller pileus, shorter stipe, larger basidiospores, and an intricate trichoderm pileipellis. Phylogenetic analysis, based on the combined rDNA internal transcribed spacer (ITS), nuc28S rDNA (28S), and RNA polymerase II subunit 2 (rpb2) genes, places C. lijiangensis in a clade with C. virgineus, C. borealis, C. yacurensis, and C. russocoriaceus. Both morphological characteristics and phylogenetic data support C. lijiangensis as a distinct new species within Cuphophyllus. This study provides a comprehensive description of the new species, colour photographs of basidiomata, micromorphological structures, and a phylogenetic tree to show the position of the new species.
