Occurrence

This deciduous moss prefers to colonize nutrient-poor, neutral to slightly acidic peat, humus or sandy soils. It can be found in heather, bog or pine forests, more rarely on silicate or limestone rocks. Typical accompanying mosses are Dicranum scoparium ( Dicranum scoparium ), Nice Widertonmoos ( Polytrichum formosum ) Pleurozium Schreberi ( Pleurozium schreberi ) Gemeines green stalk moss ( Scleropodium purum ) and Heath sofa moss ( Hypnum jutlandicum ).

Wavy-leaved fork-tooth moss is currently in decline in Europe due to the destruction of light-rich, poor woody formations and increased nutrient inputs from agriculture and the air. In recent times, fruiting plants have only rarely been observed.

features

Dicranum polysetum grows in yellowish-green lawns. Sporogons are usually formed in small groups of up to five per perichaetium. The tiny male plants are hidden in the rhizoid felt of the female. The female plants are covered with a brown felt of rhizoid that extends far upwards. The leaves are characteristically wavy, slightly one-sided and serrated irregularly. The rib ends in front of the tip and has two typical protruding lamellae on the underside.
