- The Ophiostomatales (Ascomycota) include mainly insect and mite-associated fungi, the majority of which are found on trees. Very little is known regarding the occurrence or diversity of these fungi in South America. The aim of this study was to consider their occurrence on native Nothofagus trees in the Patagonian Andes of Argentina. Isolates were collected in national parks and provincial reserves in Patagonia between 2009 and 2011. These were grouped based on morphology, and 22 representative isolates were included in phylogenetic analyses based on sequence data of multiple loci (LSU, ITS, beta-tubulin and translation elongation factor-1 alpha genes). The isolates could be assigned to ten different taxa, and included eight species of Ophiostoma s. l., one species of Leptographium, and one species in the Sporothrix lignivora complex. Three of the species are described as new, including Ophiostoma patagonicum, Leptographium gestamen, and Sporothrix cabralii. Ophiostoma quercus and O. noveae-zelandiae are reported for the first time from Argentina, and we show that the latter species is distinct from O. pluriannulatum, in contrast to a previous suggestion that they represent the same taxon.
