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.

Management:
Grazing or browsing pressure, vegetation removal may be detrimental.
