The bidentate comb cup moss ( Lophocolea bidentata ) is a drought-tolerant ( poikilohydrisches ) beblättertes liverwort and is one of the most common liverworts Central Europe. Often it is feared by gardeners as "lawn weed" as it likes to grow between grasses in lawns. However, it is a completely harmless moss.

Occurrence

The liverwort grows preferentially in moist locations on earth between other deciduous mosses and grasses. Often it can also be found on rotten wood. It also colonizes nutrient-rich and disturbed places and occurs from the plain up to the Montan level in the boreal climatic zones of the northern and southern hemisphere (circumboreal). Another disjoint occurrence can be found in tropical Africa.

features

The bidentate comb moss grows pressed against the substrate and forms yellowish to whitish-green, translucent plants that can be up to 3 cm long and 3 mm wide. They are only slightly branched and have few rhizoids on the underside . When fresh, the plants give off a noticeable odor when rubbed. The undershot, branched flank leaves are almost fully grown lengthways and divided into two long, pointed, triangular lobes on about a quarter of the leaf length. The small sub-leaves are deeply split into two columns and have a tooth on the outer edges. The formation of sporogons rarely occurs because the plants normally grow separately from the sexes. The egg-shaped perianth is triangular far downwards. The smooth spores are no larger than 18 µm in diameter.
