Sarcogyne platycarpoides most closely resembles S. pruinosa. It differs in larger apothecia (1–2 mm) with thicker margin (100–150 vs. 30–110 μm) and occasional presence of algae in the fruiting bodies. Because of the latter character, this taxon has sometimes been considered a form of Acarospora glaucocarpa. Ecology and distribution are not known in detail. The lichen is reported from calcareous rocks from lower elevations to the alpine belt. It is even known from anthropogenic habitats (Knudsen et al. 2023). Only two collections have been confirmed from the Czech Republic so far: the Hradčanské stěny in the Česká Lípa region and Nečtiny in the Plzeň region.
