Erigeron algidus is found only in the Sierra Nevada, California, extending into Nevada in the vicinity of Lake Tahoe. Leaves grow mostly at the base, and resemble many other species of this genus, being narrow, hairy, oblanceolate, unlobed and untoothed. A few smaller stem leaves are also present, arranged alternately. The unbranched stems have a covering of short glandular hairs and longer, spreading hairs.
Phyllaries, often purplish in color, either at the tip or throughout, are all the same length and also hairy, and somewhat glandular. Flowerheads have between 25 and 125 ray florets, pink or (less often) white, and a center of many small, orange-yellow disc florets. Flowerheads are produced singly, at the top of each stem.
