The light-streaked double-leaf moss ( Diplophyllum albicans ) is a liverwort species from the Scapaniaceae family .
features
The moss forms olive-green to dirty-green lawns, often loosely resting on the substrate. The slender plants are not very branched, have two rows of leaves, are 2 centimeters long and 3 to 4 millimeters wide. The leaves are bilobed, with a small, obliquely forward-facing upper lobe and about three times as large and approximately horizontally protruding tongue-shaped lower lobe.
Both leaf lobes have a distinct rib-like, well-defined median strip of elongated cells 60 to 70 µm long; the remaining leaf cells are square, 12 to 14 µm in size at the leaf edge. There are around 3 to 5 elliptical oil bodies per cell, and up to 20 in the elongated cells of the median.
Half of the perianth protruding from the bracts is egg-shaped, narrowed at the mouth, folded and covered with cilia. Light green brood bodies are often formed at the leaf tips ; these are single-celled and angular. The moss is diocesan .
Distribution and location requirements
The light-streaked double-leaf moss is common in the northern hemisphere and occurs here in Europe, Asia and North America. It is often common in Central Europe and grows mainly in lime-free areas from the lowlands to the subalpine altitude. As forest and heather moss, it inhabits silicate rocks and earthy embankments in shady, drier, but humid locations.
