This association is dominated by short sedges, and often by Trichophorum alpinum. Rhynchospora alba may reach high cover values. This vegetation type is less productive than that of other associations of the alliance Sphagno warnstorfii-Tomentypnion nitentis, containing fewer grasses and broad-leaved plants due to lower nutrient availability and permanent saturation with water or periods of shallow inundation. Moss layer is dominated by brown mosses such as Hamatocaulis vernicosus and Scorpidium cossonii, among which the calcium-tolerant peat moss Sphagnum contortum is frequently admixted. Peat layer is usually shallow. In the Czech Republic, Campylio-Trichophoretum occurs in the Třeboň basin and the Bohemian-Moravian Uplands. Ecologically similar fen habitats also occur in other regions, but they do not contain diagnostic species of this association, probably due to historical reasons.
