Iceland Moss


(Cetraria islandica), a lichen (not a moss) of the family Parmeliaceae. The thallus consists of elongated, branched brown lobes gathered in a bush with a height of up to 12 cm. Iceland moss is found in forest and tundra zones, growing mainly in pine forests, on heather moors and plains, and in the mountains. It contains the carbohydrates lichenin and isolichen-in. In the north it is an important food for reindeer.
