Plants small, green, sometimes red tinged, glossy. Stems 0.4–0.8 cm. Leaves erect to ± spreading, lanceolate to broadly lanceolate, 0.7–1.2 mm; margins serrulate to serrate in distal 1/3; costa subpercurrent; distal medial laminal cells rhomboidal, 35–60 µm, walls thin. Specialized asexual reproduction absent. Sexual condition dioicous; perigonial leaves broadly short-ovate; perichaetial leaves weakly differentiated, elongate-lanceolate. Seta orange-brown. Capsule inclined 0–20°, brown to stramineous, narrowly pyriform, neck 1/3 urn length; exothecial cells short-rectangular, walls sinuate; stomata superficial; annulus present; operculum bluntly to acutely conic; exostome teeth yellow to light brown, narrowly triangular; endostome hyaline, basal membrane scarcely exceeding capsule rim, segments slightly tapered, weakly keeled, ± perforate, cilia absent. Spores 15–21 µm, finely roughened.
Phenology: Capsules mature summer (Jun–Aug).
Habitat: Soil in mesic alpine and subalpine zones
Elevation: high elevations
Distribution
B.C., N.W.T., Wash., Europe.
Discussion
Pohlia erecta is a very rare species with soft, sometimes reddish leaves and thin-walled laminal cells. The erect sporophyte has a highly reduced peristome with short, blunt, often irregular exostome teeth, low endostomial basal membrane, and poorly developed to rudimentary segments.
