Description:Genus Description - Plants slender to moderately robust, in thin, soft, usually dull, dirty-green or yellowish mats, usually in wet places, rarely submerged. Stems creeping, freely and irregularly to subpinnately branched. Leaves mostly wide-spreading, occasionally loosely complanate, oblong-lanceolate, acute or acuminate, not channeled above, smooth; margins plane, entire or nearly so; costa simple, slender, ending at or above the leaf middle, rarely subpercurrent; cells oblong- to linear-rhomboidal, generally thin-walled, smooth, those at base broader and oblong, sometimes ± differentiated at the basal angles. Autoicous. Perichaetial leaves lance-acuminate, ± plicate.
Leptodictyum is in every way variable in gametophytic character. It differs from Amblystegium in larger size and longer leaf cells.
