|discussion=<p><i>Grimmia mollis</i>, discovered by Schimper in the Tirol of Austria, is a characteristic arctic-alpine species, frequently growing in glacial streams, sometimes over reaches of hundreds of meters. Although the species is widespread in the Northern Hemisphere, it is nowhere common. It occurs exclusively above the treeline. Because of its unique subpercurrent costa, uniform lamina of quadrate, thin-walled cells, and peculiar ecological niche, it cannot easily be confused with any other species. I. Hagen (1909) placed it in a monotypic genus, Hydrogrimmia. This concept was followed by M. F. V. Corley et al. (1981). However, there are no significant morphological characters to separate it from <i>Grimmia</i>, prompting H. C. Greven (2003) to follow, in agreement with H. A. Crum and L. E. Anderson (1981), Bruch and Schimper’s original concept. This dioicous species grows in separate male and female cushions, and capsules are produced very rarely.</p>
