A lichen characteristic by its inconspicuous thin thallus and red-brown to brown apothecia, constricted at their bases, which contain tiny ellipsoid to fusiform ascospores. The specific tiny red-brown granules present in the exciple and epihymenium and visible in sections are insoluble in KOH (Wirth et al. 2013). Lecidea erythrophaea is one of the rare epiphytic genus members in the Czech Republic. Historically, it was reported only from tree localities in the late 19th and early 20th century, from old beechwood on Mt Radhošť in the Beskydy Mts and from the Žákova hora Hill in the Žďárské vrchy uplands (Kovář 1906, 1909). Recent findings are concentrated mainly in the Šumava Mts and come usually from open scree forests, where the species was collected on a subneutral bark of deciduous trees, such as Acer platanoides and Ulmus glabra.
