Abstract

Ectomycorrhizas (ECM) of Inocybe species (Inocybaceae, Basidiomycota) formed by three host plant spe- cies ( Populus alba , Salix rosmarinifolia and Pinus nigra )ina semiarid woody steppe of Hungary were studied. To identify the fungal partners, we performed phylogenetic analyses of nucleotide sequences for the internal transcribed spacer region of nuclear DNA (nrDNA ITS) together with sequences gained from public databases. Seven Inocybe ectomycorrhiza morphotypes were morpho-anatomically characterised. Five morphotypes were identified ( I. phaeoleuca , I. psammophila , I. semifulva , I. splendens and I. subporospora ), whereas two morphotypes represented un- identified Inocybe species. Differences were discernible among the morphotypes, and they showed general anatomical characteristics of Inocybe ECM, such as the slightly organised plectenchymatic mantle (types A, B and E and the gelatinous C). The ECM of I. subporospora and I. phaeoleuca were detected from the introduced Pinus nigra . These two fungi are probably native to the area but capable of forming a novel ectomycorrhizal association with the invasive host.
