Phylogenetic Relationships, Pathogenic Traits, and Wood-Destroying Properties of Porodaedalea niemelaei M. Fischer Isolated in the Northern Forest Limit of Larix gmelinii Open Woodlands in the Permafrost Area
The phytopathogenic and wood destroying traits were studied in a basidiomycete fungus, Porodaedalea niemelaei M. Fischer, widespread in Siberian permafrost woodlands of Gmelinii larch, Larix gmelinii (Rupr.) Rupr. Numerous stands of dying out and fallen larch trees with white-rot („corrosion rot“) w...

The phytopathogenic and wood destroying traits were studied in a basidiomycete fungus, Porodaedalea niemelaei M. Fischer, widespread in Siberian permafrost woodlands of Gmelinii larch, Larix gmelinii (Rupr.) Rupr. Numerous stands of dying out and fallen larch trees with white-rot („corrosion rot“) were found in the study area. Butt rot incidence varied from 63 to 100 % depending on the stand age and raised up to 0.5-1.5 m above root collar on average or up to 9 m maximum. Root rot was also widespread, including larch undergrowth. The biodiversity of xylotrophic fungi was low, with a pronounced dominance of P. niemelaei. The main factors of dying out of L. gmelinii were infection by P. niemelaei promoted by mechanical damage of roots by reindeers during migration and climate anomalies. The cultures isolated from the fruiting bodies were identified as Porodaedalea niemelaei M. Fischer based on the combination of morphological, culture, and molecular genetic methods.
