Tortula inermis has the aspect of a Syntrichia with its ligulate, apiculate leaves and strong costa, but the plant is yellow or orange in KOH solution, and the costal section reveals a rounded stereid band. It is related to T. subulata and T. mucronifolia but the lack of a strong mucro and the narrow but nearly complete recurving of the leaf margins are diagnostic.
