A new genus, Pottiopsis is described to accommodate Pottia (Trichostomum) caespitosa. Two new combinations are made: Tortula viridifolia (=Pottia crinita) and Weissia controversa var. wimmeriana (=W. wimmeriana). Weissia controversa var. crispata is shown to be a valid name. British Didymodon reedii is shown to be a form of D. vinealis.
