Rare and threatened wood-decaying fungi in the nature protected area around Trojmezná, Plechý, and Smrčina, Bohemia Forest, Czech Republic

Abstract

The mountain forest in the south of the Bohemian Forest (Šumava National Park) is a refuge for fungi sensitive to forest management. Field research on fungi based on plots in old-growth mountain spruce forest and mixed mountain forests during the years 2003–2013 in this area revealed four critically endangered species (red-listed in the Czech Republic): Globulicium hiemale, Panellus violaceofulvus, Psathyrella cotonea and Skeletocutis stellae; and two other critically endangered species on the Bavarian Red List: Climacodon septentrionalis and Phlebia centrifuga. The ecology of red-listed wood-decomposing fungi occurring in this area is presented. We describe the forest management that is harmful to populations of wood-decomposing fungi in the study area, which was implemented to suppress bark beetle outbreaks in the most protected areas of the Šumava National Park.
