The striped fern flat moss ( Homalia trichomanoides ) is a deciduous moss species from the Neckeraceae family , the Neckermoose .
description
This moss forms dark green, shiny lawns. The secondary shoots, up to a few centimeters long, have few and irregular branches, ascending or bowing, flattened on both sides and densely leafed. Due to the leaves that are bent downwards, the cross section of the branches is curved. Habitually, the appearance is somewhat reminiscent of leafed liverworts.
The leaves are tongue-shaped to spatulate, clearly asymmetrical, around 2 millimeters long, with a thin single vein that usually extends to the center of the leaf or rarely with or without a double vein. The leaf margins are curved on one side at the base of the leaf, otherwise flat, serrated from the middle of the leaf upwards. The tip of the leaf is pointed or rounded and provided with a short point.
In the upper part of the leaf, leaf cells are rhombic to rounded six-sided and up to about 10 µm wide. In the lower part of the leaf they are more elongated, six-sided to almost linear, and shorter at the edge.
The species is fruiting quite often, spore maturity is in autumn and winter. The capsule on the 1 to 2 centimeter long, red seta is upright or slightly inclined, symmetrical, ellipsoidal to almost cylindrical, brownish, with a conical, long and obliquely beaked lid. Spores are finely papillary and 10 to 18 µm in size. The moss is monoecious .
Distribution and location requirements
The moss colonizes mainly tree bark on the bottom of deciduous trees, furthermore earth, rocks, stones and walls. It grows in mostly shady, fresh to moist, at least humid places in deciduous forests. Frequent companion mosses are Anomodon attenuatus , Anomodon viticulosus , Neckera complanata , Isothecium alopecuroides .
In Europe, this species is widespread from the plains to the mountain range, mainly in limestone areas and floodplains. In the Alps it rises to an altitude of 1200 to 1400 meters. Non-European occurrences are found in parts of Asia, North Africa and North and Central America.
