This type of deciduous moss forms loose, irregular and easily disintegrating, yellowish to brownish-green, inside brown pads or lawns that are 0.5 to 1.5 centimeters high. The leaves, which are over 2 millimeters long, are dry, adjoining roof tiles, protruding when moist or bent back, descending on the stem, ovate to elongated elliptical, hollow and with an edge that is only slightly bent towards the tip. The thin rib ends before the rounded tip of the leaf. The leaf cells are rectangular and smooth on the leaf base near the rib, about 8-15 by 30-50 µm in size, towards the edges shorter to square. Above the base of the leaf, the leaf cells are oval to rounded, thick-walled, about 15 to 18 µm in size and covered on both sides with a large papilla.
The oval spore capsules are usually completely sunk into the leaves, 8-furrowed, with phaneroporous stomata lying in a row in the middle of the capsule. The seta is very short, up to 0.5 millimeters long, the bell-shaped kalyptra is bald or has only a few hairs. The spores are about 18 to 22 µm in size and fine-black. Spore ripening is in May.
The type of moss is diocesan , it rarely produces fruit. The reproduction takes place mainly vegetatively through leaf-based brood bodies .
