Aulacomnium androgynum is a yellow-green, cushion-forming moss from the genus of the striped star moss( Aulacomnium ). It also bears the somewhat strange-sounding German name Mannweibiges Streifensternmoos and is preferred on rotten wood in swamp forests.
Occurrence
The moss prefers to grow on rotten wood and is rarely found on tree bases. However, it also colonizes earth and overground rocks in humid, lime-free places. It is particularly widespread in lowlands in swamp forests, at the edges of forests and in sparse coniferous forests, but it is rather rare in mountainous regions. It occurs all over Europe and extends to large parts of Asia . It can also be found in North America .
Identifying features
The moss forms yellow-green cushions. Individual, mostly unbranched plants reach heights of 1 to 3 cm and are extremely rarely fruiting in Europe, while in North America they develop sporogons more frequently . Its sparsely, star-shaped spreading leaves are broadly lanceolate, irregularly serrated at the tip and have no leaf border. They are no longer than 1.5 mm. The midrib ends in the leaf tip. The lamina cells are round and thick-walled. Collenchymatic , papillary cells often appear in the leaf corners . There are some elongated cells at the base of the leaf.
The moss usually reproduces vegetatively through the formation of special pseudopodia . These are brood bodies that stand on a spherical head at the tip of leafless, terminal stem sections. Sporogons are extremely rarely trained in Europe. The capsule stands on a long, reddish-brown colored seta , is elliptical in shape, is horizontal or upright, is striped and furrowed when empty. It has a double peristome . Sporogons are usually formed in early summer.
