Bryum argenteum Hewdw.
Family: Bryaceae
EN: Silvergreen Bryum Moss, DE: Silber-Birnmoos, Silbermoos
Slo.: srebrna hrušica, srebrnkasto mahovje
Dat.: March 16. and March 17. 2022
Lat.: 46.35976 Long.: 13.70495
Code: Bot_1442/2022_DSC6214 and Bot_1443/2022_DSC6298
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.
Place: Lower Trenta valley, between villages Soča and Trenta, right bank of river Soča, next to Skokar farmhouse, Trenta 2, East Julian Alps, Posočje, Slovenia EC.
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.
