Tingiopsidium is a genus of lichen-forming fungi in the family Koerberiaceae. The genus was circumscribed in 1939 by French botanist Roger-Guy Werner, with Tingiopsidium pubescens assigned as the type species. Vestergrenopsis, a genus proposed by Vilmos Kőfaragó-Gyelnik in 1940, was shown to contain a species that is the type of Tingiopsidium, and because Tingiopsidium was published a year earlier, the principle of priority makes Vestergrenopsis illegitimate, and a synonym of Tingiopsidium.
