New differential characters for Orthotrichum rogeri Brid. (Orthotrichaceae, Bryopsida)
Gametangia distribution, leaf dimorphism and endostome ornamentation and position when dry are new characters that are proposed for a safer discrimination of Orthotrichum rogeri from related species. Additionally, an updated description is given, and, since the holotype is an incomplete specimen, a complementary epitype is designated. In addition, O. stramineum. var. defluens, basionym of O. rogeri var. defluens, is typified, and both names are synonymized with O. stramineum. Finally, the presence of O. rogeri in Spain is discussed, and while the former record of this species in Spain is rejected, several new ones are reported, all of them from the Central Pyrenees.
