Abstract

Cystoderma comprises the species with heavily universal veil remnants on basidiomes, weakly to strongly amyloid basidiospores, evanescent floccose-scaly ring zone or persistent membranous ring, which were often encountered in forests and grassland. However, they were less studied than other mushroom groups mainly because of its unclearly phylogenetic position. In this study, we gathered 16 specimens from Southwest and Northwest China, where were the richest biodiversity areas in China, and produced their ITS and nrLSU sequences. The related morphological examinations and molecular phylogenetic analysis showed they belonged to eight species, of which four were new species, and named as Cystoderma lilaceum, C. pseudoamianthinum, C. rugosolateritium, C. subglobisporum, and of which two were new records from China, and they were C. granosum, C. subvinaceum. New species and new records were described in details and discussed with other species. This study not only showed the novel geographical distributions as well as high species diversity of Cystoderma in China, but also provided more research data for the further studies in mushrooms systematics.

文章题目中国囊皮菌(孢子囊门/担子菌门)4新种2新记录综述。
囊皮病包括在担子孢子上有大量普遍的面纱残余物,弱至强淀粉样的担子孢子,易逝的絮状鳞片环带或持久的膜状环,在森林和草原中经常遇到。然而,由于其系统发育位置不明确,对其研究较少。本研究从中国生物多样性最丰富的西南和西北地区采集了16个标本,建立了其ITS和nrLSU序列。形态学检查和分子系统发育分析表明,它们分属8种,其中4种为新种,命名为丁香囊皮(Cystoderma lilaceum)、假氨基酸囊皮(C. pseudoamianthinum)、葡萄囊皮(C. rugosolateritium)和亚globisporum,其中2种为中国新记录,分别为C. granosum和C. subvinaceum。对新种和新记录进行了详细描述,并与其他种进行了讨论。本研究不仅显示了囊皮菌在中国新颖的地理分布和丰富的物种多样性,而且为蘑菇系统学的进一步研究提供了更多的研究数据。
