Distribution: Restricted to the PNW.
Conservation Status: Not of concern
Ramaria araiospora is one of a small number of red-branched ramarias. It is distinguished from the others by having a single slender stipe, often with a bulbous base, non-amyloid flesh, slightly warty spores (8--13 x 3--4.5 µm), and basidia without clamps. Although the branches always are red when young, the tips may be either red (in var. rubella) or yellow (in var. araiospora); in age the whole fruitbody fades to pale reddish yellow and becomes more difficult to identify by morphology alone. The other red species in the PNW are R. stuntzii and R. cyaneigranosa. Compared to R. araiospora, the former has shorter spores (7--10 x 3--5 µm), a more massive base, reddish orange upper stipe, branches with red tips, and amyloid flesh; the latter has wider wartier spores (8--15 x 4--6 µm), overall pinkish to salmon color, and basidia with granules that appear blue in the cotton blue stain. All three of these species appear to be restricted to the PNW.
