The phylogenies obtained from the three genes were congruent and allowed differentiation of three lineages of endophytes that also presented morphological differences. One lineage corresponds to the previously described species Epichloe¨ tembladerae, which is present in a wide range of native grasses from Argentina including B. setifolius and P. alpinum. Another genotype isolated only from B. setifolius is a non-hybrid endophyte, a rare condition for the South American Epichloe¨ endophytes. Isolates of this genotype, described herein as a new variety, Epichloe¨typhina var. aonikenkana, presented waxy colonies at maturity and a low production of conidia. The third lineage, exclusively found in isolates from P. alpinum,is a hybrid between E. typhina and a common ancestor of E. amarillans and E. baconii. Isolates of this lineage produce abundant conidia that are variable in shape and size. Based on its unique phylogenetic position and morphology, we propose the new species, Epichloe¨ cabralii for this lineage. The new combinations Epichloe¨ tembladerae and E. pampeana also are proposed for the previously described Neotyphodium tembladerae and Neotyphodium pampeanum species.} }
