Phaeolus schweinitzii (Fr.) Pat.: A new record for the mycobiota of Kosovo

Root rot fungi are among the most important agents affecting the stability and longevity of coniferous forests. In this study, Phaeolus schweinitzii a characteristic brown−rot basidiomycete, is reported for the first time in Kosovo. The species was recorded in mature montane forests dominated by Picea abies in the Kuqishtë area (Pejë), where basidiomata developed at the base of living trees and on decayed root wood. Identification was based on detailed macro and micromorphological analyses in accordance with standard taxonomic literature. The occurrence of P. schweinitzii reflects long habitat continuity, stable microclimatic conditions and a high deadwood availability typical of well−preserved spruce forests. This new recording expands the known distribution of the species in the region and contributes to the understanding of fungal diversity and forest health in poorly explored montane ecosystems of Southeast Europe.
