A growing body of molecular research is discovering a high diversity of pezizalean ectomycorrhiza (EcM), yet most remain unidentified at the genus or species level. This study uncovers EcM-forming taxa within the Pezizales. 2. EcM-forming Pezizales were revealed by morphotyping and sequencing of EcM root tips from forests in Estonia and Denmark. The taxa on EcM root tips were identified using phylogenetic analyses of LSU rDNA sequences derived from sporocarps of 301 pezizalen species, and comparisons with ITS rDNA sequences. 3. Thirty-three species are suggested as EcM symbionts, representing all three major clades of Pezizales and the genera: Genea, Geopora, Humaria, Tazzetta, Trichophaea, Wilcoxina, Helvella, Hydnotrya, Tuber, Pachyphloeus, Peziza, Sarcosphaera and two Pezizaceae anamorphs. EcM of Pezizales spp. are easily distinguished by anatomy, particularly thick cell walls and stout hyphae. 4. This study demonstrates that Pezizales spp. constitute a considerable proportion of the mycobionts in EcM fungal communities in mature boreal deciduous and coniferous forests in several soil types. Fruit body sequences and EcM descriptions will facilitate identification of pezizalean EcM in future studies.} }
