The creeping shed liverwort ( Lepidozia reptans ) is a common, tiny liverwort, which mostly colonizes on rotten wood in local forests. Its German name is derived from the Greek lepis for scale and ozos for branch.
Occurrence
The liverwort prefers to colonize rotten wood or humus-rich soil in deciduous or coniferous forests. There it grows pressed against the substrate, mostly between other deciduous moss stands. However, it can also occur on lime-free rocks, on raw humus or peat. Generally it is a strongly calcifying liverwort. The creeping shed liverwort is a common liverwort, which occurs from the plains to the subalpine level in the circumboreal region in the cool, temperate latitudes of the northern and southern hemisphere.
features
The creeping scaly liverwort grows in light green to dirty yellow-green colored, flat, cover-like coatings that are pressed against the substrate. Its creeping branches are simply pinnate and only 1 to 2 cm long and about 1 mm wide. The densely placed, overshot flank leaves are about 1.5 to 2 times as long as the stem and spread out sub-square. They are divided into 3 to 4 lanceolate lobes on a third or half. The cells in the middle of the flank leaves are about 27 µm in diameter. In the lobes they are only about 24 µm in diameter. The cells are usually thin to tough-walled. They are slightly thickened at the corners. The outermost cells have a smooth cuticle . The lower leaves have 4 lanceolate lobes. Your cells can contain 10 to 15 oil bodies. The female bracts are much larger than the flank leaves and have 2 to 5 short teeth on top. The perianth is elongated and deeply three-columned.
