Atrichum crispum is frequent in the Atlantic coastal plain but also occurs at higher elevations in the mountains. It is apparently introduced in Europe (Ireland, western England, Wales, and Spain) where only male plants are known. This is a dioicous species, the plants varying in size from small to large, often yellowish green, leaves with a few low and often interrupted lamellae, and large, thin-walled leaf cells without trigones, with few or no teeth on the abaxial surface of lamina. The most distinctive microscopic character is the minute, verrucose or striate papillae on the marginal cells and teeth of the leaves (R. R. Ireland 1991). The marginal cilia on the leaf sheath of Bartramiopsis are similarly papillose.
