The swollen cypress sleeping moss ( Hypnum lacunosum ), also known as dry grass sleeping moss, can also be understood as a variety of the cypress sleeping moss ( Hypnum cupressiforme ) and is then referred to as Hypnum cupressiforme var. Lacunosum .
distribution
The swollen cypress sleeping moss is particularly characteristic of lime and base-rich, sunny, dry and relatively nutrient-poor locations. It grows preferentially on limestone and silicate rock, stony-rocky or sandy soils and settles secondarily on walls, thatched roofs and roadsides. It is prevalent in limestone areas throughout Europe, but not often.
Identifying features
The swollen cypress sleeping moss forms strong plants that are yellowish-green to golden-brown, or reddish-brown to dark green in color. Its trunks are prostrate to erect and are irregular, sporadically branched. It differs from the very similar Hypnum cupressiforme s. st. due to the swollen appearance, the short-pointed, slightly sickle-shaped leaves, which are rather suddenly narrowed from a broad-egg-shaped point into a mostly full-edged point and the relatively small sporogons. The lamina cells are also shorter (50 to 70 µm long) and wider (4 to 7 µm wide) than those of H. cupressiforme s. st. The leaves are 3 mm long and 1 mm wide.
