Plants small, forming loose tufts, dark to blackish-green. Stems erect, to 10 mm tall, reddish; in cross-section epidermal cells somewhat thick-walled, inner cells little larger, thin-walled, central strand weak. Leaves obovate to oblong, occasionally spathulate, 0.8-1(1.5) mm long, 0.25-0.4 mm wide, apex broadly acute to rounded; margins plane above, recurved below, entire to slightly crenulate distally; costae percurrent or ending several cells below apex; median cells rhomboidal to hexagonal, 24-44 µm long, to 14 µm wide, firm-walled and smooth; basal cells lax, rectangular, to 60 µm long; distal marginal cells quadrate, ca. 10-12 µm in diameter. Dioicous. Perichaetia terminal; leaves similar to somewhat longer that stem leaves. Setae elongate, 4.5-5 mm long, smooth. Capsules erect, urn short-cylindrical, 0.9-1.4 mm long, exothecial cells irregularly quadrate to rectangular, 25-60 µm long, 15-20 µm wide, firm, thin-walled; stomata few at urn base, superficial; annuli persistent; opercula conic, 2-2.25 mm long; peristome single, endostome ca. 160 µm long, papillose. Calyptrae cucullate, 1.2-1.4 mm long, smooth and naked. Spores spherical, papillose.

Hojas obovadas hasta oblongas, ocasionalmente espatuladas, 0.8-1(1.5) mm de largo, 0.25-0.4 mm de ancho, ápices ampliamente agudos hasta redondeados; márgenes planos encima, recurvado abajo, distalmente enteros a escasamente crenulados; costa percurrente o terminando varias células abajo ápice; células mediales rómbicas hasta hexagonales, 24-44 µm de largo, hasta 14 µm de ancho, con paredes firmes y lisas; células basales laxas, rectangulares, hasta 60 µm de largo; células distales del margen cuadradas, aprox. 10-12 µm de diámetro. Dioicas. Periquecios terminales; hojas similares hasta algo más largas que las hojas tallo. Setas alargadas, 4.5-5 mm de largo, lisas. Cápsulas erectas, urna corto-cilíndrica, 0.9-1.4 mm de largo, células exoteciales irregularmente cuadradas hasta rectangulares, 25-60 µm de largo, 15-20 µm de ancho, con paredes firmes y delgadas; pocos estomas en la base de la urna, superficiales; anillo persistente; opérculo cónico, 2-2.25 mm de largo; peristoma simple, endostoma de aproximadamente 160 µm de largo, papiloso.
