Evidence supporting the occurrence of a new species of endophyte in some South American grasses
Endophytes of several South American grasses were examined. The taxonomic status of endophytes in Festuca argentina, F. hieronymi, Poa huecu, and an unidentified species of Poa is evaluated. On the basis of morphological features, and rDNA and protease gene sequence data, it is proposed that this en...

The taxonomic status of endophytes in Festuca argentina, F. hieronymi, Poa huecu, and an unidentified species of Poa is evaluated. On the basis of morphological features, and rDNA and protease gene sequence data, it is proposed that this endophyte is different from several other endophytes examined from North American, South American, and European species of Festuca and Poa.
