Tortula modica ( Pottia intermedia . (Turner) is NR) is a moss - kind from the family pottiaceae .
features
The moss often grows in flocks and forms low, loose lawns. The simple or split stems are less than an inch high. The upright leaves are slightly larger at the tip of the stem than the lower, ovate, lanceolate to spatula-shaped and quickly narrowed to the short tip. When dry, the leaves are twisted and twisted. The leaf margins are flat or (mostly) bent back, the rib emerges as a short or long yellow-green spike tip. The lamina cells in the upper part of the leaf are smooth to slightly papillary, roundish square to hexagonal, about 12 to 25 micrometers wide and have barely thickened cell walls.
The species almost always forms abundant spore capsules, these are raised clearly above the leaves on the seta , which is about 4 to 10 millimeters long, and are oblong ovoid to short cylindrical. The uncovered capsule is not enlarged at the mouth. Peristome teeth are absent or only rudimentary, the capsule lid is beaked crookedly, the kalyptra is smooth, spores are finely papillary and 20 to 34 micrometers in size. Spore ripening time is from autumn to spring.
Location claims and distribution
Tortula modica is a pioneer moss on the open ground in mostly sunny locations. The soil can be weakly acidic, neutral to basic, especially clay, loamy or sandy to interspersed with gravel. Calcareous soils are often preferred. The species often grows in fields, in vineyards or gardens, on roadsides or on ruderal areas, even on earth-covered walls.
In Europe, the moss is widespread, especially in the temperate zone, in lower areas. There are also deposits in Asia, North and Central America, North Africa and Australia.
