Hertelidea botryosa (Fr.) Printzen & Kantvilas

It is a species characteristic of relic pine forests. It grows in large crusts, most often on slowly rotting sunlit pine wood. Rarely, it passes to bark at bases of pines. In the neighbouring Slovakia, the species is also known from oak forests, as the hard, slowly decaying oak wood has similar properties as pine wood. In the Czech Republic, this species has recently been confirmed from the Šumava Mts and its foothills, the Brdy Hills and the Jeseníky Mts. Most historical reports from the country turned out to be wrong. Usually, it was confused with the common species Placynthiella icmalea (Palice 1998). Hertelidea botryosa is often sterile and thus it may be partially overlooked.
