This is the species-richest association within the class Scheuchzerio-Caricetea nigrae in the Czech Republic, in both the herb and moss layer. The most frequent dominant species are the reddish peat moss Sphagnum warnstorfii and the cotton grass Eriophorum latifolium. Brown mosses such as Scorpidium cossonii may occur in wet depressions within a matrix of hummocks and carpets of calcium-tolerant peat mosses. In contrast to other associations of the alliance Sphagno warnstorfii-Tomentypnion nitentis, this association lacks several boreal species while it may contain some species with temperate distribution, such as Carex davalliana. Currently it occurs especially in fen grasslands that are mown for hay, from cool colline to montane areas in the Czech Republic.
