  • notes   Slo.: srebrna hrušica, srebrnkasto mahovje - Habitat: Dry, former pasture near an abandoned farm house, semiruderal, skeletal, calcareous ground; dry, mostly sunny, open place; exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevations 553 m (1.800 feet), alpine phytogeographical region. - Substratum: shallow, sandy, poor soil. - Comments (pertain to pictures in Flicker album Bryum argenteum): Bryum argenteum is a common and cosmopolitan moss (absent only from Antarctica). It can be easily recognized by its typical growth: cylindrical shoots about 1 cm or less long with adpressed leaves grow in usually compact, low cushions or mats sometimes of considerable size. They have a characteristic silvery-whitish appearance particularly if dry. This I due to the fact that the cells of the upper part of the leaves lack chlorophyll, hence the shots look greenish silvery-whitish (see Fig. 2M). The moss frequently grows in anthropogenic habitats and on disturbed ground, but also in the wild in many different habitats like on poor soils, and rocks. - Ref.: (1) Ian Atherton, Ed., Mosses and Liverworts of Britain and Ireland - a field guide, British Bryological Society (2010), p 596.
