The common Krausblattmoos ( Ulota crispa ) is a deciduous moss species from the Orthotrichaceae family .
features
The common Krausblattmoos is very similar in the characteristics and location requirements of the sister species Bruch's Krausblattmoos . It forms round, yellow-green cushions up to 2 centimeters in size. The ovoid base, linear-lanceolate, gradually pointed, about 3 millimeters long leaves are strongly curled when dry, more or less protruding when wet. At the edges of the leaf base there are several rows of rectangular, water-white cells. The lamina cells in the upper part of the leaf are papilose, rounded-oval and mostly 9 to 12 µm in size (somewhat smaller than in Bruch's Krausblattmoos ). Sporophytes are about 3 to 5.5 millimeters long (without lid), the capsule is young and moist, smooth and oval, later deeply grooved, slender, wide-mouthed and narrowed below the mouth. The peristome is double, the outer peristome teeth are dry knocked back. The moss is monoecious and has regular fruit. Spore ripening time is in spring and summer.
ecology
As an epiphyte, the common Krausblattmoos grows preferably on the bark of deciduous trees, more rarely on conifers, preferably in humid forests such as stream valleys, headwaters or moors, but also in light-rich forest edge locations. Common companion mosses are Orthotrichum species, Ulota bruchii , Frullania dilatata , Radula complanata or Hypnum cupressiforme . This species, which used to be common in the past, is sensitive to air pollution and has been severely decimated in some areas.
Occurrence
This type of moss is common in the northern hemisphere. In addition to Europe, it occurs in parts of Asia, on the Atlantic Islands, in North America, in North Africa. There is another occurrence in Tasmania.
