The strains CBS 125177, CBS 125178, and CBS 125181 had initially been identified morphologically as Fusariumandiyazi. Two separate clusters were visualized by using MALDI-TOF MS, one comprising three strains including the type strain of F. andiyazi, and another with strains CBS 125177, CBS 125178, and CBS 125181 ( Fig 5). This indicates that MALDI-TOF MS has a potential to distinguish closely related and morphologically identical Fusarium species. Here, the MALDI-TOF MS data are used as an additional parameter in our polyphasic classification of this cryptic species.
