The fruit body consist of numerous branches that arise from usually two to four large primary upright branches, which themselves originate from a single thick, fleshy base; the overall dimensions of the fruit body are tall by wide. Unlike many larger Ramarias, R. fennica fruits bodies are usually taller than they are wide. The surface of the branches is smooth, and they can range in color from olive-grey to olive-umber to smokey-yellow, grayish-tan, or yellow brown. The primary branches are darker–olive-brown tinged with violet in young specimens. The thick and fleshy stalk is white below, with color becoming the same as the branch color in the upper part of the stem. The flesh is white, firm, and brittle.
