The glossy flat moss ( Plagiothecium laetum ), also known as Lush flat moss , is a species of deciduous moss that is often split into two types, Plagiothecium laetum and Plagiothecium curvifolium (= Plagiothecium laetum var. Curvifolium ), the curved-leaved flat moss . Since there are flowing transitions between these two forms, merging them makes sense.
Distribution and location requirements
It is a common deciduous moss in deciduous and coniferous forests, which prefers lime- and base-poor , relatively nutrient-poor , fresh to moist locations. The moss colonizes both humus and rotten wood; more rarely it also grows on rocks and on tree bases. It is distributed almost over the entire northern hemisphere in the temperate latitudes.
description
The moss forms soft, very shiny lawns. It has 1 to 2.5 mm long, slightly asymmetrical leaves. With var. Curvifolium , the leaves are somewhat hollow, more or less longitudinally wavy, and the leaf tips are bent downwards in a hook-shaped manner when moist. The leaf margins are serrated in the area of the leaf tip. The single or double central rib never reaches the middle of the leaf. At the corners of the base sheet, there are rectangular sheet vane constituting a clearly delimited band from 1 to 5 rows of cells, said leaf leaf hinge at var. Laetum normally is narrower than var. Curvifolium
