Abstract
Cystinarius is a small genus belonging to the family Cortinariaceae, distinguished by its distinctive combination of small basidiospores and presence of both cheilo- and pleurocystidia, a combination that is rarely found in other genera within the Cortinariaceae. To date, this genus consists of only two subgenera and includes seven recognized species. Previously, only a single specimen of Cy. crassus was reported from China. Based on the analysis of 17 newly collected specimens, supported by morphological evidence and two-locus phylogenetic inference, five species, namely, Cy. fulvellus, Cy. longipes, Cy. shennongensis, Cy. crassus, and Cy. paurigarhwalensis, were recognized. Among them, the former three species are new to science, whereas the last one is new to China. This study provides comprehensive taxonomic descriptions and a detailed identification key to the Cystinarius species discovered in China.
期刊介绍：
International in coverage, Mycologia presents recent advances in mycology, emphasizing all aspects of the biology of Fungi and fungus-like organisms, including Lichens, Oomycetes and Slime Molds. The Journal emphasizes subjects including applied biology, biochemistry, cell biology, development, ecology, evolution, genetics, genomics, molecular biology, morphology, new techniques, animal or plant pathology, phylogenetics, physiology, aspects of secondary metabolism, systematics, and ultrastructure. In addition to research articles, reviews and short notes, Mycologia also includes invited papers based on presentations from the Annual Conference of the Mycological Society of America, such as Karling Lectures or Presidential Addresses.
