Atrichum altecristatum is an acrocarpous moss and generally grows in green cushion like mats reaching 3cm in hight. The preferred habit of this moss is moist soil in shade. The capsules are raised above the leaves in a slightly curved fashion. The operculum (lid) of the capsule is long and narrow. Upon reaching maturity the lid opens and exposes the peristome teeth
