A new species belonging to Didymodon sensu lato, Vinealobryum guangdongensis , is described and illustrated from Nanling National Forest Park of Guangdong, China. It is characterized by noteworthily thick‐walled cells of the cauline central cylinder, ovate‐lanceolate leaves that are appressed when dry, acuminate to acute leaf apices, leaf base abruptly broadened and quickly narrowed to the insertion, leaf margins recurved in proximal 2/3 to 3/4, short‐excurrent costa with 0–1 layer of ventral stereids, laminal cells with conical or elliptical papillae either over the lumina or over transverse walls, presence of gemmae in the leaf axils, and KOH laminal color reaction red to reddish orange. This new species is compared with the most similar species and its ecology is discussed.
