Additional Information at NatureServe

Diagnostic Characteristics:
The white leaf tip of O. diaphanum is immediately diagnostic within the genus and makes this very common species look more like a Schistidium than an Orthotrichum . It grows in small tufts of narrow, upright shoots, up to 1 cm tall, usually with abundant capsules. Leaves are 2.5┐4 mm long, and capsules are 1.5 mm long. Unripe capsules are covered by a hairless, light green calyptra, whilst ripe capsules are light brown and slightly furrowed when old and dry. The 16 light brown outer peristome teeth are reflexed when dry.

Grazing or browsing pressure, vegetation removal may be detrimental.
