Myriolecis antiqua (J.R. Laundon) Śliwa, Zhao Xin & Lumbsch

This poorly known taxon is characteristic by the presence of xanthones in apothecia, which make thalline margin yellow, C+ yellow to orange (the reaction also in discs) and UV+ pink. In Europe, it has been reported from limestones, basic silicates and anthropogenic calcareous substrates. Its occurrence in the Czech Republic is questionable – there is only a single historical record under the name L. conferta from diabase rocks in Motol (Servít 1930). However, the herbarium specimen in PRC is in a very bad condition and it was possible to confirm only its affiliation to the genus.
