摘要

Fusarium is a ubiquitous genus that includes mycotoxin producers and pathogens of animals, plants, and other organisms. Four new Fusarium species obtained from the University Recife Mycology Culture Collection (Micoteca URM), Brazil, are described in this study based on the morphology and phylogenetic analysis of DNA sequences of calmodulin (CaM), RNA polymerase largest subunit (RPB1), RNA polymerase second largest subunit (RPB2), and translation elongation factor 1-alpha (TEF1). The newly discovered species were nested within the Fusarium concolor (FCOSC), F. incarnatum-equiseti (FIESC), and F. sambucinum (FSAMSC) species complexes and were named as F. teslae, F. mourae, F. primavesiae, and F. pulchrum. This research contributes to the knowledge of new fungal species from tropical regions and contributes to information related to the morphological and phylogenetic diversity of Fusarium.
