Macrofungi of urban Tilia avenues and gardens in Hungary

Abstract

Macrofungal investigations were performed in gardens and avenues planted with Tilia spp. between 2009 and 2020 in Hungary, focusing on the Budapest area. Lime tree (Tilia) is recently one of the most favorable commonly used ectomycorrhizal tree in urban landscaping in Budapest, similarly to other European cities. As a result of 71 sampling occasions in total 60 epigeous and hypogeous macrofungal species belonging to 22 families and 33 genera were documented. The nrDNA ITS barcoding region of 56 specimens was sequenced. Fifty-nine species were identified, while one interesting Inocybe sp. could not be determined. Phylogenetic analyses of the most frequently collected family, Inocybaceae, including three genera and 17 species were performed. The genera Russula and Tomentella, two preferred ectomycorrhizal symbionts of Tilia in urban environments were also analyzed. Inocybe alluvionis, I. amelandica, Mallocybe siciliana and Pseudosperma aureocitrinum were reported for the first time from Hungary. The taxonomic status of other species is also discussed.
