General Description
Plants: Single or in thin turfs (patches of erect shoots), 0.5-2 mm (FNA 2007); stems occasionally branched (Lawton 1971).

Leaves: Tongue-shaped (lingulate) to nearly circular, very concave, 0.5-1.5 mm; margins smooth, distally somewhat wavy to fine-toothed; apex margin curved inwards to nearly open. Costa strong (FNA 2007), usually over half the leaf’s width (Lawton 1971), extending nearly to the leaf apex (subpercurrent), with filaments of 2-5 cells covering the costa as well as part of the adjacent 2-layered area of the blade (2007).

Leaf Cells: Basal laminal cells thin-walled and elongate; median laminal cells thick-walled and transversely elongate; costa filament cells nearly spherical to cylindrical, thin-walled, the terminal cell of each filament nearly spherical to almost conical and thickened at apex (FNA 2007).

Phenology
Capsules maturing (March-) May-August (FNA 2007).

Diagnostic Characteristics
A. brevirostris and A. rigida are similar. However, A. brevirostris is synoicous and the operculum conic. A. rigida is dioicous and the operculum long-beaked (FNA 2007).
