Odontoschisma denudatum (Odontoschisma denudatum)
Description
Odontoschisma denudatum is a liverwort species of the family Cephaloziaceae and belongs to the group of leafy liverworts. German-language names include Barred Chalice Livermoss or Naked Chalice. Odontoschisma denudatum makes yellow-green to brown, loose to dense turf. The low-lying, low-branched plants are up to about 2 inches long. At the ends they are directed upward and often extended like flagellas, with whitish brood patters at the top. The slanted, unterschlächtig arranged flank sheets are up to 0.75 millimeters long, roundish-ovate and indistinctly lined. Lower leaves are usually clearly formed only at the shoot tips. They are up to 0.35 millimeters long, bidentate or undivided. Laminazelles are about 23 × 30 μm in the middle of the leaf and have very marked nodular to square corner thickenings. There are 3 to 5 large oil bodies per cell. The species is dioecious . Bracts are 2- to 3-lobed. The perianth is elongated ovate and deeply longitudinally oblong, with notched or toothed muzzle. Spores have a size of 8 to 10 microns. The moss rarely breeds. Sporenreifezeit is in the spring. Odontoschisma denudatum grows in forests and bogs in shady, moist to wet, nutrient-poor locations and inhabits here rotten wood, peat soils, Rohhumus and occasionally sandstone. Companion mosses are mainly Tetraphis pellucida, Dicranodontium denudatum, Lepidozia reptans and Blepharostoma trichophyllum . The general distribution is subozeanisch. In Central Europe it is particularly prevalent in montane situations, rarely in the plain. It also occurs in Western and Northern Europe, parts of Asia and North and Central America.
