Ptilidium pulcherrimum , also known under the German names Schöne Federchenmoos or Zierliches Federchen-Lebermoos , is a representative of the order Ptilidiales and is one of the leafy liverworts.
features
Ptilidium pulcherrimum grows in green to red-brown, dense, flat lawns. The individual plants are up to two centimeters long, prostrate and branched one to two times. The branches are short, barely a millimeter wide and densely leafed. Flank leaves are grown almost across the stem, they are divided up to three quarters of their length into three to four lanceolate to pointed-triangular lobes. The lobes are about 6 to 10 cells wide at the base and densely ciliate at the edge. These eyelashes are up to 0.5 millimeters long and single rows. Sub-leaves are in two parts or undivided and also ciliate on the edge. The lamina cells are round in the middle of the leaf, 30 to 35 µm in size, have thickened cell corners and contain numerous oil bodies ; the cells of the leaf eyelashes are rectangular.
The species is diocesan . Male plants are smaller and grow in separate lawns or mixed with female plants. Sporogons are not uncommon. Perianthia are cylindrical to club-shaped, wrinkled at the top and have a narrowed and ciliate mouth. Spore capsules on the long seta are oval, spores are red-brown, punctured, rough and 25 to 27 µm in size.
ecology
The moss often grows on tree bark, especially on trunk bases and in the root area of conifers, and on rotten wood, more rarely on silicate rock. Locations in shady to light, humid locations in montane altitudes are preferred. Frequent accompanying mosses are Hypnum cupressiforme , Dicranum scoparium , Dicranum montanum or Lophocolea heterophylla .
distribution
Ptilidium pulcherrimum is distributed around the circumference. In Europe it is particularly widespread in mountain forests. Here the occurrences extend south to Northern Italy and Bulgaria. Outside of Europe, it occurs in Asia and North America.
