Thallus: like Sphaerophorus globosus but forming dense, pale grey-brown tufts to 4 cm, without any red-brown tinge but often with a pinkish tinge when wet. Branches fragile, erect or partially decumbent, equally dichotomous, sterile branches all of similar width, 0.6-0.8 mm diam., fertile branches often distinctly larger and wider than sterile ones and often also with ± coralloid branchlets, the surface dull grey-brown or grey, often somewhat roughened.
Anamorph: no information available.
Teleomorph: ascomata apothecia, very rare, 1-2 mm diam. Ascospores 8-10 μm long, ellipsoidal, deep violet to blue-black.
Chemistry: medulla C–, K–, KC–, I–, Pd–, UV+ blue-white (sphaerophorin, ± hypothamnolic and ± squamatic acids).
