Micranthes nivalis is a perennial herb which grows on damp, shady, base-rich rocks and cliffs where it normally occurs in crevices and on ledges in locations where it cannot be crowded out by competing plants. In Britain its altitudional range is 365 metres (1,198 ft) at Quiraing in the western Isles to 1,210 metres (3,970 ft) on Ben Lawers in Perth & Kinross, although it has been claimed as high as 1,300 metres (4,300 ft) in the Cairngorms. It grows to a height of 5–20 centimetres (2.0–7.9 in) with a leafless, hairy stalk the flower is greenish white turning reddish as it ages with 5 petals and 5 sepals. The leathery, greyish green, rhomboidal leaves make up a rosette at the base of the stem and lie close to the soil surface and are only sparsely haired.

is distinguished from var. nivalis by smaller inflorescences and narrower leaves. It is known only from the Shickshock Mountains of the Gaspé Peninsula of southeastern Québec. It has been suggested that this may be a hybrid of M. nivalis and M. tenuis; further study is warranted.
