Oxyrrhynchium is a genus of deciduous mosses from the Brachytheciaceae family with sub- cosmopolitan distribution.
description
The medium-sized plants form loose, pale green to brownish-green, shiny lawns. The creeping trunks are irregularly to fairly regularly branched and very loosely or in some places more densely catcat-like with leaves. The branches have kitten-like leaves and are half-flattened to sometimes clearly flattened. The stem leaves are upright-splayed to splayed, smooth, egg-shaped (widest at a seventh to a third of the leaf length) with a short or long tip; the edges are sawn to finely sawn. The leaf rib extends to the middle of the leaf or almost three quarters of the leaf length and emerges as a thorn on the back of the leaf. Branch leaves are similar to or strongly differentiated to the stem leaves, in the latter case more elliptical with the widest part of the leaf at 1/2 to 1/3 of the leaf length and shorter pointed.
The species are mostly diocesan . The seta is long and rough, rarely smooth, the egg-shaped and curved capsule inclined to horizontal, the capsule lid long beaked.
Systematics and types (selection)
The species of the genus Oxyrrhynchium were often assigned to the genus Eurhynchium . Recent research results speak for the independence of Oxyrrhynchium .
According to Stech & Frey, Oxyrrhynchium contains 22 species worldwide, according to other sources it comprises 10 to 15 species. The following species are found in Europe:
