Sharpiella seligeri ( Syn. Herzogiella seligeri , Isopterygium seligeri , Plagiothecium seligeri ) is a deciduous moss and was named after the Silesian pastor Ignaz Seliger . It almost always produces fruit and is therefore particularly easy to recognize by its characteristic curved capsules.
Identifying features
Sharpiella seligeri is only relatively small plantlets from, are usually crawling, dull colored green to yellowish and grow in relatively loose blankets. The irregularly branched stem is no longer than 3 cm long and is often provided with a few root hairs . The arching branches are up to 2 cm long. The leaves protrude in the lower part, but in the upper part they are more or less close to the stem. At the ends of the shoots, the leaves are one-sided, but otherwise weakly sickle-shaped and long and finely pointed. The leaf margin, usually serrated to the base, has a short or missing rib. The leaf wing cells are indistinctly highlighted, ovate and yellowish- hyaline in color. The lamina cells are 10 to 16 times as long as they are wide and are often spotted at the base of the leaf. The reddish-colored seta has a spore capsule that is characteristically curved in a worm-like shape and has an elongated cylindrical shape. It is often streaked when dry and releases greenish colored spores.
Occurrence and location requirements
Sharpiella seligeri is a widespread, lime-avoiding forest moss, which prefers shady, moist to wet locations in coniferous, deciduous, broken and bog forests. In addition to soil, it colonizes dead bark, tree stumps and rotten wood. However, it can only be found here in small-scale stands with numerous populations . It is widespread throughout Europe as far as the Arctic Circle. In the south, its populations extend to North Africa. Otherwise it can also be found in North America and parts of Asia.
