Calliergonaceae is a moss - family in order Hypnales .

description

The often large plants are golden to brown or reddish in color. The stem cross-section has a central strand. There are leaf-like pseudoparaphyllia. The leaves are straight or sickle-shaped, smooth or wrinkled, the rib is simple and usually long. The cells in the middle of the leaf are linear; Leaf-wing cells are usually differentiated, often inflated, and hyaline.

The species are dioecious or autocratic (antheridia and archegonia on different branches on the same plant). The seta is elongated and smooth, the spore capsule horizontal, curved, cylindrical.

The chromosome number is n = 10, 11, 20-22 or 24.

Occurrence

The mosses grow in damp to wet locations. Occurrences are found in the northern and southern hemisphere in temperate to arctic and Antarctic zones as well as in tropical montane areas.

Systematics

The mosses were traditionally assigned to the Amblystegiaceae family . On the basis of molecular data, they were separated from this and placed in the new Calliergonaceae family (Vanderpoorten et al., 2002).

Worldwide there are 5 genera with 21 species in the family:
