Additional information: As we collected this sample, very early one cloudy morning in densly wooded surroundings, the light was so bad that taking pictures was nearly impossible. You don't miss too much: the sampling site lies among some pines, directly to the south of a road between Fürstenzell and Ortenburg (see map above).
