Pyrenula laevigata (Pers.) Arnold

A species macroscopically similar to Acrocordia gemmata. It differs from other Pyrenula species in forming a thin pale (often whitish) thallus, which is K+ yellow, and the absence of anthraquinones in the perithecia (K-). It prefers a smooth bark, e.g., of hazel or beech. It grows from lowlands to lower montane elevations. Within central Europe, it is currently more abundant only in the Alps. It is extremely rare in the Czech Republic, recently only known from a few trees in the Žofínský prales nature reserve. There are historical records from the first half of the 20th century from Moravia and Silesia (see the Vězda & Liška 1999 catalogue).
