Included in B. erectum in Michigan Flora.
Moist to dry deciduous forests, lowland forests, moist thickets, sandy pine forests, and coniferous swamps.
In addition to the pubescence features noted in the key, B. aristosum typically has 3–5-nerved lemmas, florets ca. 8–10 mm long (excluding awn) and 0.7–1.3 mm wide, anthers not over 4 mm long, and more than 15 cilia per 5 mm of leaf margin. Brachyelytrum erectum has more strongly (5–) 7–9-nerved lemmas, at least the larger florets ca. 10–12 mm long and 1–1.6 mm wide, anthers more than 5 mm long, and fewer than 10 cilia per 5 mm of leaf margin. Widespread in Michigan, but more common northwards.
