Prasiola calophylla is a terrestrial green alga in the class Trebouxiophyceae. It is one of the few macroalgae species that can survive extreme temperatures. It is also known for its ability to withstand high levels of solar radiation, changing salinity, and dessication.228
Taxonomy.
The species was first described by Captain Carmichael in Lismore, Scotland in 1826 under the name "Bangia calophylla". It was reclassified as "Prasiola calophylla" by Kutzing in 1845.
Occurrence.
"P. calophylla" is found in cold temperate regions of the Northern Hemisphere, typically on coasts above the high tide line in the supralittoral zone227 and in damp places inland, like moist soil, rocks, and trees in cold temperatures with humid climates.416
It has been reported in the United Kingdom and in continental European cities like Innsbruck in Austria. It was reported in Hokkaido, Japan for the first time in 2016.
"P. calophylla" has also been reported in parts of Antarctica, including streams in McMurdo Sound,180 southern parts of Victoria Land on glacial walls, and rarely in Ross island streams.88 However, more recent studies using gene sequences suggest the reports from Antarctica are a different species, not "P. calophylla."
