Chaenotheca laevigata Nádv.

Chaenotheca laevigata is characterised by the immersed thallus containing trebouxioid algae, by the relatively tall fruiting bodies covered with yellow pruina, and by the ellipsoid ascospores. It grows on acidic tree bark and on wood of snags and stumps. It is a predominantly boreal-montane lichen and therefore shows the preferences for coniferous to mixed forests. It is a rare lichen in central Europe, possibly because it is a species of late succession stages (Selva 2003). Only two records of the species in the Czech Republic have been published: on a hornbeam snag in the valley of the Jihlavka river near Hartvíkovice (Nádvorník 1938, Suza 1944) and on bark of a spruce stump on Mt Praděd in the Hrubý Jeseník Mts (Malíček et al. 2019).
