Coniocarpon cinnabarinum DC.

A rare species, characterized by the pruina on apothecia which is white but orange-red at margins. From the similar C. elegans it differs in longer spores (> 20 μm) and rounded to slightly lobate apothecia. It grows in open humid deciduous forests, mainly on ash, more rarely also on hornbeam, beech and oak, from lowlands to sub-montane zones. In Europe, it occurs mainly from the sub-Mediterranean belt to the sub-oceanic area of the temperate belt. It is rare in central Europe and has clearly declined during the last century. There are only historical records from the 19th century from the area of the Czech Republic, but the collections require revision. It is currently considered extinct.
