Bryum subapiculatum is a rarely fruiting, weak competitive pioneer moss , which mainly reproduces vegetatively through rhizoid-based brood bodies ( rhizoid gems ). It belongs to the moss group Bryum atrovirens agg.
features
The diocese deciduous moss forms 0.5 to 1 cm large plants and grows loose-grass in small herds. Usually it can be found sprinkled between other mosses with only a few small plants. The lanceolate leaves are unframed and have a reddish leaf base. In contrast to the closely related Bryum capillare, they are gradually pointed. The reddish-colored leaf vein emerges briefly from the leaf. The lamina cells in the middle of the leaf are hexagonal and about 10 to 16 µm wide. The lamina cells at the base of the leaf are rectangular in shape. The moss has brownish colored rhizoids, on which red-brown, rhizoid-based brood bodies (rhizoid gems) often occur, which are around 150 µm in size.
Occurrence
Bryum subapiculatum prefers lime-free, base-rich or slightly acidic, loamy-clayey to sandy, sometimes humus-containing, dry to moist soils. It colonizes stubble fields, raised soil, overgrown stones, fallow fields and other rudderal, often disturbed locations. Its occurrence is essentially limited to the northern parts of Central Europe . It occurs mainly in Germany , France , Iceland , the British Isles and Scandinavia . It is rarely found in the Mediterranean area . It penetrates into the westernmost parts of Russia . Individual representatives have also been found in New Zealand and North America .
