Iceland moss (Cetraria islandica) is a shrub-like lichen (and not a moss at all) with an erect, much branched thallus which forms entangled mats. The lobes of the thallus are brown to olive green in colour, fringed and may be slightly incurved, especially when dry. Iceland moss grows on poor, acidic soil, generally in the ground layer of pine woods, on trees, rocks and walls, in mountain and moorland regions of central and northern Europe and other northern parts of the world. In arctic regions it forms an important food source for reindeer, and has also long been eaten and used in medicine. Research Iceland Moss
