Tortula Moss

Description:

Family: Pottiaceae
It grows in patches, tufts and neat cushions less than 1 cm tall. A long, smooth, silvery, excurrent nerve projects from the rounded leaf tip, making the moss look hoary grey when dry. The tongue-shaped leaf blade is 2 to 3.5 mm long, and twists and curls when dry, but the leaves spread away from each other when moist. The margins are recurved almost to the tip. The less common var. aestiva has a very short, excurrent green nerve. Narrowly cylindrical capsules develop from spring to autumn.

Musgo que aparece con frecuencia, formando céspedes almohadillados. Las plantas miden 3 – 5 mm de altura, son de color verde, con tonos glaucos a veces.

Habitat:

T. muralis is the commonest moss on many mortared or base-rich walls – both of brick and stone – and can tolerate some shade. It also grows on concrete, roof tiles and other man-made structures, as well as outcrops of natural, base-rich rock, and much less commonly on trees and wood.

Uno de los musgos más frecuentes, crece sobre rocas, calizas principalmente; es capaz de resistir la contaminación, por lo que también es posible encontrarla en muros de hormigón de las ciudades.
