Placynthium dolichoterum (Nyl.) Trevis.

A rare montane taxon similar to the common P. nigrum, from which it differs in longer ascospores and an inconspicuous prothallus (Czeika & Czeika 2007, Thüs & Schultz 2009). The only Czech published record is sterile and comes from a classic lichenological locality – the Studénková hole Mt [= Červená hora] in the Hrubý Jeseník Mts, where it was collected on dying bryophytes in cracks of humid calcareous slate rocks (Vězda 1960, as Placynthium cf. pluriseptatum var. pluriseptatum). In central Europe, it usually grows on enriched silicates (such as slates), but also on limestone, often on humid, periodically inundated rocks near water courses or in cracks of vertical rocks with water seepage (Thüs & Schultz 2009).
