A yellow-green lichen forming scattered, but sometimes aggregated, somewhat lobate, often subsquamulose areoles up to 350 µm in diameter. Soralia initially develop along the sides of the areoles. Soredia are fine, 20–50 µm in diameter. Apothecia are rather rare; the asci contain eight spores. A nearly identical species is C. xanthostigmoides, which has not yet been confirmed from Europe. Records published under that name from the Czech Republic in recent years refer to C. rubrisoli. In the sterile state, it is also difficult to distinguish from C. efflorescens.
It grows on trunks and twigs of a wide range of tree species in open landscapes as well as forests. Well-developed fertile specimens have mostly been found on half-shaded bark (most often on Salix) in humid deciduous forests. Its distribution in Europe and in the Czech Republic is still poorly known, but it probably is widespread. However, no records are so far known from southern Europe. The pattern of records in the Czech Republic suggests that C. rubrisoli prefers middle to higher elevations. The species was described from China.
