RESUMO

During a survey of fungi in native forests in Chile, several unidentified isolates of Diaporthe were collected from different hosts. The isolates were characterized based on DNA comparisons, morphology, culture characteristics and host affiliation, in accordance with previous descriptions. Phylogenetic analysis of the ITS region, combined with partial tub2 and tef1 genes, showed that the isolates formed three distinct groups representing three new taxa. The three new species of Diaporthe, Diaporthe araucanorum on Araucaria araucana, Diaporthe foikelawen on Drimys winteri and Diaporthe patagonica on Aristotelia chilensis are described and illustrated in the present study.
