Plants small, gregarious, blue-green, covered with bluish 'bloom'; on soil over rock. Stems erect, 5-10 mm high, branched above; in section with large central strand, inner cortical cells enlarged, thin-walled, outer cortical cells small, incrassate, in three layers. Leaves erect-flexuose dry, patent wet; lanceolate-subulate, 2.5-3.5 mm long; apex acute; margins plane above, reflexed at mid-leaf, irregularly serrate above. Costa excurrent; in section guide cells 4, large, ventral stereid band to 3 cells thick, ventral surface cells larger, incrassate, dorsal stereid band large, 5-6 cells thick, dorsal surface cells larger, incrassate. Laminal cells rectangular to quadrate throughout, somewhat incrassate, some upper lamina cells prorate. Autoicous. Perigonia terminal on short lateral branches. Perichaetia terminal; leaves subulate above oval base, 4-5 mm long. Seta straight, 6-8 mm long; capsule erect, elliptical, 1.0-1.5 mm long, weakly grooved dry, yellow-brown; exothecial cells rounded-rectangular, quadrate at mouth; peristome 0.25 mm high, teeth divided to base into two linear processes, occasionally irregular, strongly papillose, red-brown; operculum long-rostrate, 0.5-0.8 mm long; calyptra cucullate; spores 17-20 µm, round, papillose.

Leaves 1-2.5(-3.5) mm, proximal leaves small, the distal and perichaetial leaves gradually acuminate, ± subulate from a lanceolate base; costa with a single row of guide cells, and both adaxial and abaxial stereid bands, or adaxial stereid band sometimes weak or rarely absent; lamina cells often irregularly 2-stratose towards the apex and occasionally elsewhere. Seta to 15 mm. Capsule with operculum to 1 mm. Spores 15-20(-22) µm, greenish to yellow-brown.
Plants small, gregarious, blue-green, glaucous. Stems 5-10 mm long, branched above. Leaves erect, flexuose when dry, patent when wet; narrowly ovate, subulate, 2.5-3.5 mm long; apex acute; margins irregularly serrate; costa excurrent. Upper laminal cells rectangular to quadrate. Capsule exserted, erect, elliptical; peristome teeth divided to base. Recognised by its bluish ‘bloom' and erect, branching stems.
