Plants small to medium-sized, dark red to red-green, rarely entirely green. Stems 0.5–2(–3) cm, julaceous, without metallic sheen, older stem sometimes densely radiculose. Leaves rigid, imbricate, crowded, dark red to red-green, sometimes dark green, ovate, distinctly concave, 1–2(–3) mm; base not or weakly decurrent; margins revolute proximally, plane distally, entire to finely serrulate distally, limbidium absent; apex rounded to broadly acute, not cucullate; costa reddish, not reaching apex or rarely percurrent, awn absent; basal laminal cells occasionally pigmented, in 1 row; proximal cells abruptly quadrate, with scattered short-rectangular cells, 1–2:1; medial and distal cells hexagonal, (40–)50–70 × (16–)18–24 µm, (2–)3–4:1, walls firm, parallel to costa. Specialized asexual reproduction rare, by rhizoidal tubers, on rhizoids arising from leaf axils, orange-red to red-brown, 100–200 µm. Seta ± straight, red, red-brown, or purple. Capsule nutant, dark red-brown, short-pyriform, 2–3 mm, neck short. Spores 14–18 µm, papillose, yellow-brown.
Phenology: Capsules mature Jun–Aug (summer).
Habitat: Damp shaded siliceous rock, soil in rock crevices, montane

Discussion
Imbribryum muehlenbeckii is similar to small forms of I. alpinum, but has strongly concave, ovate leaves, short distal laminal cells, and a weak costa. Most material from western North America can be referred to an undescribed species; see discussion under 1. I. alpinum.
