Campylostelium saxicola is a tiny moss with glossy, crisped, or sometimes circinate leaves; it grows on shaded boulders in forests over most of its range but in rock shelters in the southern portion. Campylostelium saxicola is wide-spread in the flora area but infrequently collected due to its inconspicuous nature. Its small delicate stature, smooth calyptra, and usually flexuous-curved seta distinguish it from Ptychomitrium.
