Plants in dense mats, bright to dark green or olive green. Stems 0.4–1 cm, weakly julaceous to stringlike. Leaves erect when moist, ovate, weakly concave, 0.2–1 mm; base green; margins plane distally or rarely recurved proximally; apex acute, not cucullate, not hyaline; costa not reaching apex, apiculus absent or very short, 1 or 2 cells, hyaline; proximal laminal cells short-rectangular, at least in alar region, 12–18 µm wide, 2–3: 1; distal cells hexagonal, (25–) 30–55 × 10–16 µm, usually 3: 1, walls thin to somewhat thickened, not distinctly incrassate. Specialized asexual reproduction absent. Sporophytes unknown.

Discussion

Bryum veronense was first collected from the Front Range of Colorado near Boulder by W. A. Weber and R. C. Wittmann, in soil filled crevices in sandstone. The plants agree well with named European material, although they are a dark olive green rather than the bright green of European material. Since then the species has been collected from Ontario, Quebec, and Vermont. This species is similar to B. calobryoides, but lacks the strongly julaceous stems, strongly concave leaves, and cucullate apices of that species.
