Lecidea sarcogynoides has an immersed thallus and relatively large apothecia (often over 2 mm) with flexuose margin. Therefore, it may resemble members of the genus Sarcogyne from which its species name is derived. Microscopically, it is characterized by the hymenium of a conspicuously red-purple colour that becomes even more intense in KOH.
It is a sub-cosmopolitan lichen with a Mediterranean tendency. It grows on dry sunlit exposed siliceous rocks rich in minerals. In the Czech Republic, it occurs at lower and middle elevations. Reliable material comes only from southern Moravia and the Middle Vltava region. Historical records listed in the Catalogue by Vězda & Liška (1999) come usually from higher elevations, e.g. in the Šumava Mts, and are doubtful. In the past, the species might be mistaken for the unrelated Adelolecia pilati which also contains purple pigments in apothecia, but these are apparent only in KOH.
