Its fruit bodies, which resemble sea coral, grow up to 16 cm (6.3 in) tall and feature whitish to light yellow branches with pinkish to reddish tips.

The fungus was described as new to science in 1973 by Currie Marr and Daniel Stuntz in their monograph on the Ramaria of western Washington.

[2] Ramaria rubripermanens is somewhat similar in appearance to Ramaria botrytis, but can be distinguished from that species by the persisting pink to red coloration of the branch tips, and the lack of a staining reaction in the branches.

The basidia, which feature a clamp at their bases, are club-shaped, usually four-spored, and measure 31–62 by 7–11 μm.

[1] Ramaria rubripermanens is known from the western United States, including Washington, Idaho, and Oregon.
