Hal.) Ochyra, an obscure and poorly known spe− cies originally described from Îles Kerguelen as Grimmia cupularis Müll. Hal. and subse− quently reported from a single station in the Antarctic, is re−assessed taxonomically. It is considered to be a distinct species of sect. Conferta, closely related to S. amblyophyllum (Müll. Hal.) Ochyra et Hertel, from which it differs in its distal− and mid−leaf areolation of short, isodiametric, quadrate to shortly rectangular cells; stouter costa, 50-75 µm wide in the distal and median part, semi−terete to subrectangular in cross−section and prominently convex on the dorsal surface, (2-)3−stratose above, 3(-4)−stratose below; leaf margins regu− larly 2-3−stratose in 1-3 rows of cells forming fleshy, bulging limbidia; presence of a dis− tinct central strand; and finely roughened to nearly smooth peristome teeth. S. celatum (Cardot) B.G. Bell from South Georgia and Tierra del Fuego is considered to be conspecific with S. cupulare. Some details of the type specimens of both species are illustrated. The geographical range of S. cupulare is evaluated and it is considered to be an amphiatlantic subantarctic species. A new record of the species from Livingston Island in the Antarctic is provided and a key to species of Schistidium in Antarctica is given.
