The aim of this study was to determine the destructive capabilities of the two white rot fungi Pleurotus cornucopiae (Pc) and P. eryngii (Pe) compared with the standard fungus Trametes versicolor (Tv) on beech wood samples after 60 days of incubation. Understanding of the white rot decay is important as it is necessary for the development of effective solutions for wood protection. Measurements of mass loss, chemical, mechanical properties and light microscopical investigations were conducted prior to and after incubation. Mass loss of samples was found to be 9-22 % depending on fungi species. Impact bending strength is not as sensitive as presumed in classical literature. Light microscopy analysis revealed that decay patterns were similar for both fungi. Wood cell wall thinning, fungal colonization hyphae were also the same for both fungi. Results indicated considerable wood attack by both Pleurotus species, Pc being more destructive than Pe.
