摘要：The diversity of Coprinopsis species has been studied from the coprophilous habitats throughout the Punjab state from 2007 to 2011. Twelve taxa namely C. cinerea, C. cothurnata var. equsterca, C. foetidella, C. lagopides var. lagopides, C. lagopus, C. macrocephala, C. nivea, C. pseudonivea, C. radiata, C. radiata var. macrocarpa, C. scobicola and C. vermiculifera are reported. Out of these, C . radiata var. macrocarpa and C. cothurnata var. equsterca are proposed as new varieties and Coprinus foetidellus is transferred to Coprinopsis foetidella. Two species, viz. Coprinopsis pseudonivea and C. vermiculifera are first time records from India. In this paper, all these taxa are described, illustrated, and compared with similar species. A dichotomous key to aid in their identification is also given
