New records from the moss flora of Iran

Despite Iran’s climatic diversity, only ۴۷۵ moss species have been reported from the country. The number of species increased to ۴۷۶, including the species introduced here. So far, ۵۹ species and three varieties of mosses have been reported from Lorestan Province; with the addition of the specimens presented in this research, this number rises to ۶۰ species and four varieties. In this study, which focused on the diversity of mosses in Lorestan Province, a total of ۱۲۰ moss specimens were collected through extensive field surveys during multiple trips. These specimens were subsequently identified using reliable references. In this paper, Lewinskya tortidontia and the Pterygoneurum ovatum var. muticum are reported for the first time from Iran. Lewinskya tortidontia differs from L. affine by the uniform distribution of hairs on the calyptra and the shape of the operculum, which is broad at the base and suddenly narrows into a short beak.  Pterygoneurum ovatum var. muticum is distinguished from the other variety of this species P. ovatum var. ovatum, by the absence of a costa at the leaf apex.
