Calicium notarisii (Tul.) M. Prieto & Wedin

A lichen characteristic by a yellow thallus, relatively immersed fruiting bodies and submuriform ascospores. Often, it occurs only in the pycnidial stage. Its typical substrate is dry, weathered hard wood in the natural as well as worked form (such as fences). It prefers the oak wood, but exceptionally it grows also on conifers. Generally, C. notarisii is more abundant at lower elevations and in continental areas. Therefore, it partly vicariates a similar, primarily mountain species, C. tigillare. In Scandinavia, the lichen usually grows on a worked timber of buildings (accompanied for example by Lecanora saligna and Pseudothelomma ocellatum) and seems to prefer dust–impregnated substrates (Areskoug & Thor 2005). Nádvorník (1942) also mentions the species is slightly nitrophilous. In Europe, the lichen is widespread but rare. From the Czech Republic it is known only from two localities, in both cases from oak wood. Cyphelium notarisii was found in 2001 in Pohansko in southern Moravia and in 2020 at the locality of Vraní skála in the Podyjí National Park.
