Blindia caespiticia ( lawn blind moss ) is aspecies of deciduous moss in the Seligeriaceae family .
features
Blindia caespiticia forms dense, brownish-green, shiny cushions with plants 0.5 to 3 centimeters high. The upright to slightly one-sided leaves are narrowed from an egg-shaped, hollow base into a long, blunt awl tip. The strong rib fills the awl tip completely. The thick-walled lamina cells are elongated, rectangular to linear. The cells on the leaf base are brownish in color. The clearly differentiated leaf wing cells are enlarged and roughly square.
The spore capsule is sunk into the bracts, with a very short neck, almost spherical and upright. There is no peristome . The capsule lid is short and crooked, it is lifted up together with the columella when the spores ripen. The yellowish, finely granular spores are about 14 micrometers in size. The species often fruit.
Fruiting plants are easy to distinguish from Blindia acuta because of the sunken spore capsules . If there are no capsules, it is difficult to distinguish between the very similar moss plants.
Location claims and distribution
The moss grows on shady, moist to wet, base-rich silicate rock, especially on limestone shale. In the Central Alps it occurs scattered or rarely and only at altitudes of around 1200 to 2700 meters, in the Limestone Alps there are only individual sites. There are other occurrences in Scotland and Scandinavia.
Systematics
The kind was earlier as the only one in the genus Stylostegium as Stylostegium caespiticium (F. Weber & D. Mohr) Bruch & Schimp. posed. Today it is generally assigned to the genus Blindia .
