A lichen with the amyloid medulla (I+ blue) and characteristic anatomy of the apothecial margin, which is brownish-orange inside and forms a conspicuous orange-red solution when KOH is added to the microscopic slide (leptocline-type according to Scheidegger 1993). Macroscopically it resembles, for example, the species Adelolecia pilati.
The lichen grows on rain-exposed surfaces of siliceous rocks. In Europe, it is rather a rare member of the genus with a boreal-montane to arctic-alpine distribution. There are a few historical records from the Czech Republic, mostly from the high mountain ranges (see the Catalogue by Vězda & Liška 1999). Recently it is known from the Žalostná rocks on Mt Keprník in the Jeseníky Mountains, Velká Pleš in the Křivoklát region and the Hůrka Hill in Slavkovský les Highlands.
