COMMENT

Three infraspecific taxa were reported from Algeria whose identity has not been revised after its description ( Ros et al. 2013): Didymodon tophaceus var. brevicaule (Schimp.) Boulay , reported by Bescherelle (1882) as Trichostomum tophaceum var. brevicaule , and later compiled by Jelenc (1955a) from Alger, le long de la route de Saint-Eugène; Didymodon tophaceus fo. acutifolius (Schimp.) Zodda, reported by Jelenc (1955a) from Constantine and Gorges de la Chiffa, ruisseau des Singes; and Didymodon tophaceus fo. recurvifolius (Boulay) Willd., reported by Jelenc (1951, 1967) from Monts de Tlemcen, Plateau de Lalla Setti, 1000 m, and by Jelenc (1955a) from Constantine and Monts de Tlemcen, Beni Snous. Due to the notable morphological variability of the species ( Jiménez 2006), most probably these names do not have any taxonomical value.
