Diagnosis

Gametophytes leafy, simple or irregularly branched. Leaves lanceolate, keeled, intermittently bordered, declined and entire, with a slightly clasping base and gradually narrowed, acute apex, arranged relatively closely on the stems in spiral order. Costa does not reach the leaf apex. Leaf blade composed of thin–walled, elongated cells. Sporophytes lateral. Seta quite long, surrounded by perichecial leaves covering the base of the capsule. Capsules erect, shortly cylindrical or oval. Operculum conic and shortly rostrate.
