Pohlia nutans

Pohlia nutans, the nodding thread-moss, is a species of moss in the family Mniaceae.[2] It has a Cosmopolitan distribution, found on all seven continents; Europe, Iceland, Siberia, Japan, North America, Greenland, the Andes of South America, South Africa, Tasmania and nearby mainland Australia, New Zealand, and the Antarctic Peninsula and Mount Rittmann in Antarctica.[1] An extremophile, it is resistant to cold, drought, salt, acid, heavy metals, and intense UV radiation.[3][4][5][6]
