Syn.: C. citrina var. flavocitrina (Nyl.) W. R. Watson

Saxicolous, on calcareous and siliceous rocks, very common on artificial substrata (mortar, concrete, walls, etc.), nitrophilous and tolerant to air pollution, rarely lignicolous or corticolous.

Belgium: CC.

Luxembourg: CC.

France: CC.

This species has been confused with C. citrina for a long time. They frequently grow together, C. flavocitrina normally being less nitrophilous and more frequent.
