Indoor fungal destroyers of wooden materials Their identification in present review

The wood-destroying fungi traditionally were separated from one another primarily on a basis of their sporocarp and/or strain morphology. Their diversity and simple macro- and micromorphology of fungal structures have been major obstacles for more rapid progress in this regard. However, over the past two decades, there has been substantial progress in our understanding of genetic variability within traditionally recognized morphospecies. In this study we have overviewed genetic variation and phylogeography of macrofungi, which are important destroyers of wooden materials indoor of buildings. Several morphologically defined species of these fungal destroyers (Coniophora puteana, C. olivacea, C. arida, Serpula himantioides) have been shown to actually encompass several genetically isolated lineages (cryptic species). The protective efficacy against cryptic species within traditionally recognized morphospecies through laboratory tests (EN 113) and field trials (EN 252) might be sufficient to better prognosis of decay development in wooden materials for hazard assessment and for proper conservation and management plans. © 2018 Statny Drevarsky Vyskumny Ustav.This work has been supported by grants from the Grant Agencies of the Ministry of Education, Science, Research and Sport of the Slovak Republic (VEGA No. 1/0286/17 and KEGA No. 025UMB-4/2017) and the Faculty of Sciences of the University of Ostrava, Czech Republic (SGS No. 16/PřF/2016).
