The fork-toothed moss ( Dicranum ) are a genus of deciduous mosses from the family Dicranaceae .

features

Mosses of this genus are usually strong plants in often extensive lawns or larger cushions. The mostly upright, simple or forked stems can be up to 10 centimeters in size and are covered with a more or less dense, whitish to reddish brown felt of rhizoids . The leaves are usually lanceolate, often crescent-shaped, one-sided, more rarely straight, often hollow and sharp or bluntly pointed at the top, have differentiated leaf wing cells and a simple rib that extends or protrudes to the tip of the leaf. The leaf cells are oblong-rectangular to linear, in the upper part of the leaf often shorter to rounded-square. The long setahas an upright to inclined and straight or curved spore capsule with a long beaked lid and 16 peristome teeth forked to the middle .

Systematics and types

In the past, some species were separated into the genus Orthodicranum (Bruch & Schimp.) Loeske , for example the species Dicranum flagellare ( Orthodicranum flagellare ) or Dicranum montanum ( Orthodicranum montanum ). In accordance with the Stech & Frey system, this spin-off is not followed here.

Information on the global number of species varies greatly depending on the sources: according to Stech & Frey there are 92 species, according to other sources 140 to 150 species.
