Description

Silvery moss has erect stems in loose to dense tufts, silvery-white, 0.4-1.0 cm high. Leaves 0.5-1.0 mm long, often with recurved, short-pointed tips, closely overlapping each other, cells rectangular, thin-walled, most cells of upper leaf surface lack chlorophyll, costa (nerve of leaf) ending below the apex. Seta (stalk subtending capsule) 0.8-2.0 cm long arising from the apex of the stem. Capsules 1-2 mm long, cylindrical in shape, longer than wide, rarely produced. Gemmae (small round group of a few cells serving in vegetative reproduction) not produced.

Diagnostic Characteristics

Small, compact silvery-white moss. Leaves with recurved apiculate apices with costa (nerve of leaf) ending below the apex. Gemmae lacking.
