Tomentella (Thelephorales, Basidiomycota) in Nothofagaceae forests of Patagonia, Argentina:mycorrhizae of new species. Tomentella is a mycorrhizal genus whose presence in temperate, tropicaland circumpolar forests has been widely reported. It typically forms ectomycorrhizae (EM), but alsoorchidioid, ericoid, monotropoid and arbutoid symbiosis. Tomentella EM morphotypes have consistentmorphological and microscopical features, for which reason their description and characterization is auseful tool in environmental research. In this study, detailed morpho-anatomical descriptions of 4 EMTomentella species associated with Nothofagus pumilio, N. dombeyi, N. antarctica, Lophozonia alpinaand L. procera forests are presented, also molecularly determined at species level, and their ecologicalrelevance is discussed. The morphology and type of exploration of the 4 EM were consistent with previousreports for Tomentella species. These EM have no specificity for a single Nothofagaceae host and can befound in at least two species of this family. Our results show that the study of ´EM´ morphotypes´ morphoanatomyconstitutes an irreplaceable tool for quantification and analysis of the functional diversity of EMcommunity
