The Arctic-alpine bloom moss (Schistidium frigidum) is a species in the genus Schistidium. It is currently classified as Least Concern on the IUCN Red List. Native to Europe, inhabiting ecosystems characteristic of the region.

Chubby Grimmia

The Chubby Grimmia (Schistidium flaccidum) is a small acrocarpous moss in the family Grimmiaceae, found on acidic rock surfaces across northern Europe and Scandinavia. Despite its common name, the species belongs to the genus Schistidium rather than Grimmia, although the two genera are closely related within the family. S. flaccidum grows in compact cushion-forming tufts on siliceous boulders, cliff faces, and rocky outcrops in humid, often montane environments. The moss is documented from Norway and Sweden, where it occurs in habitats typical of boreal and subarctic rock communities. Like other Schistidium species, it produces sporophytes with exserted or immersed capsules that release spores for dispersal. The genus Schistidium is one of the largest among saxicolous (rock-dwelling) mosses, with many species distinguished by subtle differences in leaf shape, costa characteristics, and peristome structure. C. flaccidum has not been evaluated for conservation status by the IUCN and is listed as Not Evaluated. Rocky habitats support diverse bryophyte communities that are sensitive to air quality and moisture regimes. The ecology of Schistidium species on Scandinavian rock communities has been the subject of detailed phytosociological studies.
