Silver moss - Silver moss

Japanese: ギンゴケ - ぎんごけ

A moss of the family Scleractinaceae that is most commonly found around human habitation. It is found all over the world, even in Antarctica, but it is highly resistant to dry air and pollution and grows in large cities. In Japan, it grows on stone walls, concrete, soil, and even roofs of houses, but it is also common in mountainous areas, and is found on the summit of Mount Fuji. The plants are small, silvery or whitish-green, and form a dense, velvety mat. The stems are thin, 3-10 mm tall, densely overlapping, and broadly oval. The cells at the tip lack chloroplasts and are transparent, which makes the plant appear white.

Japanese:

人家の周辺で最も普通なカサゴケ科の蘚類。世界中に遍在し，南極大陸にまで分布しているが，大気の乾燥や汚染に対しても強い抵抗性を示し，大都市にも生育する。日本でも，人家の石垣，コンクリート，土の上をはじめ屋根の上にまで生えるが，山地にも多く，富士山の頂上にも分布している。植物体は小さく，銀色または白緑色で，密なビロード状のマットをつくる。茎は細く，高さ3～10mm，密に重なり，広卵形，先端部の細胞は葉緑体を欠き透明で，このために植物体が白く見える。
