Type Information: Basionym: Lichen chalybeiformis L. Type: Bryoria chalybeiformis (L.) Brodo & Hawksw.

Biogeography: Northern hemispheric; arctic (circumpolar, aparently bipolar), subarctic, boreal, subantarctic, and antarctic; montane, upper montane, and subalpine. Continent: Northern America. Checklist records: Sonoran Desert and United States and Canada (continental).

Ecology: Biotroph; lichenized; terricolous, occasionally lignicolous, or saxicolous (on granite in Arizona); growing sun-exposed, under conditions which are dry or moist.

Lichen Photobionts: Primary photobiont present; chlorococcal. Primary photobiont taxonomy: Trebouxia; Trebouxiaceae; Trebouxiales.

Thallus: Fruticose, subdivided into main or not subdivided (branches) parts, and secondary (branchlets) parts, isotomic-dichotomous or anisotomic-dichotomous (towards the tips); lobes elongate or linear; erect; branches terete (most branches) or occasionally applanate (moderately flattened); separate thallus parts (.3)-.5-1-(2) mm wide.

Upper Surface: Black (olive), brown, olive, or dark brown, usually glossy (shiny), smooth; foveate; not pseudocyphellate; wrinkled (twisted and folded (foveolate)); not isidate; with isidiomorphs (true spinules absent, but often with spinulose lateral branches); not sorediate or sorediate (but sparse); soralia laminal, eroding from the tip of tubercles, isidiate (occasionally spinulose). Lower Surface: Absent.

Reproduction Strategy: Only known as sterile, asexually reproducing form or with sexual (and possible asexual) stages (unknown).
