Barbula convoluta is a type of moss that grows on earth or overground rock and is widespread and common in Central Europe. The scientific name would roughlymean Bärtchenmoos rolled up in German.
description
The species forms loose to dense, conspicuously yellow-green luminous pads or lawns. The plants reach a height of about 1 cm, sometimes up to 2 cm. At least denser cushions are dark brown rhizoid-felted in the base .
The leaves are ovate, lanceolate to almost tongue-shaped. When dry they are weak but clearly bent, when wet they stick out upright. The leaf margin is flat or at most curled up at the base. However, the perichaetial leaves are rolled up like a tube along their entire length.
The species can reproduce vegetatively through rhizoid gems that are formed in the rhizoid felt .
The slightly curved capsules sit on a yellow seta . The peristome teeth are twisted to the left three times.
Distribution and location requirements
The species is cosmopolitan .
It grows on earth, overground rock or old walls, where it prefers calcareous substrate. Together with Ceratodon purpureus , it penetrates into the inner cities, where it can form mass populations, for example in pavement cracks, at ruderal spots or on roadsides.
