Brachythecium tommasinii ( Syn. Cirriphyllum tommasinii , German tender-nerved hair leaf moss ) is a deciduous moss species from the Brachytheciaceae family .
Identifying features
The moderately vigorous to more delicate plants grow in light green to dark green or tanned, shiny lawns. The primary creeping stems adhere to the substrate with rhizoids . The tufted, branched secondary stems arise from them. The branches are often long, pointed.
The stem leaves that run down, are not or slightly longitudinally folded and have an egg-shaped to lanceolate base, are rather suddenly narrowed into a hair-shaped tip, the length of which is about a third of the total leaf length. The leaf length is 1.8 to 3.5 millimeters, the margins are whole to slightly serrated and flat or folded over narrowly at the base. The simple leaf vein, which becomes thinner towards the top, extends approximately to the middle of the leaf. The branch leaves are only up to 2 millimeters long.
The leaf cells are square to rectangular at the leaf base, linear in the center of the leaf, 6 to 12 µm wide, 40 to 110 µm long and thin-walled.
The purple seta is up to 20 millimeters long. The inclined, oval and slightly curved spore capsule is 1.5 to 2.4 millimeters in length, and its lid is beaked.
Distribution and location requirements
Occurrences of this kind can be found in Europe and beyond in the Caucasus. It is mainly widespread in the mountainous regions of Central Europe. The moss grows in forests in moderately shady to shady and dry to fresh locations, preferably on limestone and slate.
