Fragile Campylopus Moss (Campylopus fragilis)


Campylopus fragilis (German Fragile Krummstiel Moss , Bruchbl-ttriges Krummstiel Moss ) is a moss - kind from the family leucobryaceae . Campylopus fragilis forms loose to dense, up to 3 or 4 centimeters high, green to yellow-green lawns with whitish translucent leaf bases. The stems bear a red-brown rhizoide felt, they are tufted on the top and thickly leafy. The leaves are 4 to 5 millimeters long, straight, stiff erect, lanceolate-pectoral with gutter-shaped pegs and toothed leaf tips. They are somewhat narrower towards the blade, so that the widest point is approximately one eighth to one fourth of the blade length. The leaf rib occupies approximately one third to one half of the leaf width at the base of the leaf. The cross-section of the rib has a layer with large hyaline cells on the upper side (ventral side), a middle layer of deuterial cells in usually the same number and dorsal stereoid groups. The laminar cells are hyaline below, rectangular and thin-walled, irregularly shaped at the top, in the majority approximately rhombic. Leaf wing cells are not differentiated. At the tip of the sprout are often very numerous small lanceolate brood-leaves, which serve the vegetative propagation. Capsules are rarely present.
