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.
