Coniocarpon fallax (Ach.) Grube

Similarly to the related species C. cinnabarinum, it is a rare, hygrophilous and quite thermophilic lichen. It differs in shorter ascospores (≤ 20 μm) and narrower irregularly radially branched apothecia. It grows on a smooth bark of deciduous trees (e.g., hazel, ash and hornbeam) or on firs, in open forests with high air humidity from lowlands to sub-montane zones. In Europe, it is distributed from the Mediterranean to more humid areas of the temperate belt. In the Czech Republic, only a single published historical record is known: from beech and hornbeam near Hradec Králové by Mann (1852). However, it is doubtful (see Servít 1959) and the herbarium material requires revision.
