Base-rich fens without calcium carbonate precipitation, often with calcium-tolerant sphagna, e.g. Sphagnum contortum, S. subfulvum, S. teres and S. warnstorfii. The sphagna are accompanied by other mosses such as Paludella squarrosa and Tomentypnum nitens, sedges, sundews and other calcicole as well as calcifuge vascular plants classifying this habitat among the most species-rich mires.
