Orthotrichum
Orthotrichum diaphanum
The moss genus Orthotrichum includes about 200 species that grow mainly in temperate latitudes epiphytic on rocks or on bark of trees worldwide. In German-speaking mosses of the genus are also called gold hair mosses. Many species are very good pointers for the quality of the air quality. Because many types of air pollution are greatly diminished or threatened. Meanwhile, the situation has eased again in some regions of Germany. Mainly anthropogenic SO2 emissions were responsible for the disappearance of mosses. So you are good bioindicators of air purity, fall sharply even at low load increase.
Identifying
Species of the genus Orthotrichum form of upright stems. Your are oval to lanceolate shaped, raw-edged, abutting or projecting leaves are not curled when dry. The leaf margins are, however, usually rolled over or repulsed. The midrib extends to the blade tip and occurs only when the nature Orthotrichum diaphanum than hyaline glass top. The lamina cells are frequently papillae, rectangular to round six-sided.
The Seta the Sporogone is extremely short. The capsule is therefore sunk into the leaf rosette. These towers above most only slightly. It has 8 to 16 furrows. The calyptra is conical to bell-shaped. The peristome is usually configured twice.
Gold hair Moose can also reproduce vegetatively by forming blattbürtiger propagules.
