Coprinopsis hispida is described and illustrated as a new species from lowland northern Pakistan. Morphological characters and phylogenetic analyses based on nuclear rDNA internal transcribed spacers (ITS1-5.8S-ITS2 = ITS) were used to clarify the taxonomic identity of the species. Coprinopsis hispida belongs to C. section Alopeciae and is distinguishable from related species by having a medium-sized basidioma, convex to plane pileus which is covered with silvery-white fibrils, ellipsoid to amygdaliform basidiospores measuring 8.5–10.5 × 5.5–7.0 µm, smooth, dark brown, with a central germ-pore that is 1.0–1.5 µm wide. Morphological characters are discussed and compared with other species of the section. With this report, the number of species of Coprinopsis known from Pakistan is raised to six.

Coprinopsis hispida：来自巴基斯坦北部低地的一个新的类公鸡物种

Coprinopsis hispida被描述和说明为来自巴基斯坦北部低地的一个新物种。基于核 rDNA 内部转录间隔区 (ITS1-5.8S-ITS2 = ITS) 的形态学特征和系统发育分析被用来阐明物种的分类学身份。Coprinopsis hispida属于C. section Alopeciae，与相关物种的区别在于具有中等大小的担子瘤，凸向平面菌盖，覆盖有银白色的纤丝，椭圆形至杏仁状担子孢子，尺寸为 8.5-10.5 × 5.5-7.0 µm，光滑, 深棕色，中央胚孔宽度为 1.0-1.5 µm。对形态特征进行了讨论并与该部分的其他物种进行了比较。有了这份报告，物种的数量从巴基斯坦已知的Coprinopsis被提高到六个。
