In western North America, Diphyscium foliosum is terrestrial in tundra sites, often in blowouts; it is also found as humid perpendicular sods pendent from ledges and on rock in canyon walls; in eastern North America it is found on banks and horizontal surfaces in forests. The unique golf-tee-like protonemal flaps, which can be excavated from the rhizoids, are a distinctive family trait.
