Abstract

In our recent paper on the relationships of 21 European Hypnum taxa we introduced the name Hypnum subcomplanatum Hedenäs, Schlesak & D. Quandt as a new name at the species level, based on the basionym Hypnum cupressiforme var. subjulaceum Molendo (Schlesak et al. 2018). We were aware that H. cupressiforme var. subjulaceum had already been elevated and combined at the species rank (Stereodon subjulaceum (Molendo) Loeske & Osterwald [Verh. Bot. Vereins Prov. Brandenburg 49: 65. 1907)], but unfortunately overlooked that Hypnum subjulaceum Besch. was not validly published. The latter therefore cannot block a species level combination in Hypnum based on H. cupressiforme var. subjulaceum Molendo (Art. 53.1 of the Code). Because no homonym issues exist, the epithet ’subjulaceum’ has priority when combined under Hypnum. The new combination follows:
