During fungal surveys between 2012 and 2014 in pine-dominated forests of the western Himalayas in Pakistan, several collections of (Agaricales, Inocybaceae) were made. These were documented, based on morphological and molecular data. During this work, three new species came to light, which are here formally described as , and . These species belong in the genus Matheny et al. (2019) = Pseudosperma clade Matheny (2005) = sect. Rimosae s.s. fideLarsson et al. (2009). Macro- and micro-morphological descriptions, illustrations and molecular phylogenetic reconstructions of the studied taxa are provided. The new species are differentiated from their close relatives by basidiospore size and colouration of basidiomata. Molecular phylogenetic relationships are inferred using ITS (ITS1-5.8S-ITS2), nrLSU and mtSSU sequence data. All three newly-described taxa likely share an ectomycorrhizal association with trees in the genus . In addition, five names are recombined in , and . These are , , , and .
在2012年至2014年期间,对巴基斯坦喜马拉雅山西部以松树为主的森林进行真菌调查时,采集到了几种(伞菌目,丝盖伞科)标本。基于形态学和分子数据对这些标本进行了记录。在此过程中,发现了三个新物种,在此正式将它们描述为、和。这些物种属于Matheny等人(2019年)的属 = Matheny(2005年)的假精子分支 = 根据Larsson等人(2009年)的狭义裂皮组。提供了所研究类群的宏观和微观形态描述、插图以及分子系统发育重建。这些新物种通过担孢子大小和担子果颜色与它们的近缘种相区分。利用ITS(ITS1 - 5.8S - ITS2)、nrLSU和mtSSU序列数据推断分子系统发育关系。所有这三个新描述的类群可能都与属的树木形成外生菌根共生关系。此外,在、和中有五个名称进行了重新组合。它们是、、、和。
