Great Basin Naturalist


Twenty-six taxa of Grimmiaceae are listed from Nevada, all representing the genera Grimmia and Rhacomitrium. Rhacomitrium heterostichum (Hedw.) Brid. var. heterostichum and Grimmia atricha C. Muell & Kindb. ex Mac. & Kindb. are listed for the first time as occurring in Nevada. Within the state, the Mohave Desert the Great Basin desert, and the Sierra Nevada display unique composition of members of the Grimmiaceae. Grimmia anodon is the most widespread moss in the state. Others, such as Grimmia rivulare, G. conferta, and G. alpicola inhabit only the montane environments of northeastern Nevada.
