Dichodontium pellucidum , also known as translucent double tooth moss , is a calcareous deciduous moss that occurs in damp to wet locations in the temperate latitudes of the northern hemisphere .
description
The dioecious plants form dark green to yellow-green lawns and are 2–4 cm high, sometimes significantly higher.
The broadly lanceolate to tongue-shaped leaves are moist, protruding or bent back, slightly twisted to curled when dry. The base of the leaf slightly encompasses the stem. The leaf margin is smooth or slightly wavy in the lower part of the leaf, notched towards the tip. Overall, however, the shape of the leaf and the formation of the leaf edge are very variable.
The leaf vein ends just before the leaf tip. The cells of the leaf surface are strongly nipple .
The smooth, upright to horizontally inclined, egg-shaped capsule sits on a relatively short, yellow-brown seta .
distribution
Dichodontium pellucidum is mainly found in the mountains of the northern hemisphere. It rarely occurs in the lowlands.
It grows in chalky, wet locations, for example on stones by streams, on damp walls or on sand on stream banks.
