Calypogeia neesiana ( Nees Bart cup moss ) is a liverwort - kind from the family Calypogeiaceae . The species is named after Christian Gottfried Daniel Nees von Esenbeck (1776-1858), a German botanist and natural philosopher.
features
Calypogeia neesiana makes flat, olive-green to yellow-green lawns. The egg-shaped, roof-tile arranged flank leaves are rounded at the tip or trimmed transversely to sometimes shallowly edged and directed diagonally upwards towards the tip of the trunk. The leaf margins are lined with one or two rows of more or less clearly elongated cells. The cells in the center of the leaf are approximately 30-40 by 40-60 micrometers in size. Oil bodies are only present in the cells of the leaf margin and base, but not in the middle of the leaf. Lower leaves are wider than the stem, roughly circular and slightly margined to a short V-shaped incision. Occasionally, brood bodies are formed. The moss is monoecious .
Location claims and distribution
The strictly lime-avoiding moss demands a very acidic, mostly organic substrate and settles in partly sunny to shady, wet areas in raised bogs or moor forests, on open peat soils, on raw humus or on more decomposed rotten wood.
The distribution extends over much of the northern hemisphere. In Europe it is scattered or rarely with a focus on high-montane, precipitation-rich locations.
