Abstract Fusarium isolates obtained as endophytes from healthy leaves of Handroanthus chrysotrichus (Bignoniaceae) in the Atlantic Forest of north-eastern Brazil were characterised morphologically and phylogenetically on the basis of partial rDNA sequences encompassing the second largest subunit of RNA polymerase II, translation elongation factor EF-1 alpha, and β-tubulin genes. A novel species within the Fusarium lateritium species complex (FLSC) is described as Fusarium massalimae. Isolates of F. pseudocircinatum of the Fusarium fujikuroi species complex (FFSC) were also isolated as endophytes from leaves of H. chrysotrichus. Mating type gene analyses suggested that obtained isolates of F. massalimae and F. pseudocircinatum are heterothallic. Keywords Endophytes . Fusarium pseudocircinatum . Fungal taxonomy . One new species
Introduction Fusarium species have a widespread distribution and are soilborne pathogens of many native and crop plants (Aoki et al.

2014; Sandoval-Denis et al. 2018). Mycotoxins produced by Fusarium species can contaminate agricultural products and present a health risk (Tima et al. 2016). Furthermore, they can inhabit or associate insects (O’Donnell et al. 2012; Santos et al. 2019, 2020) and spiders, amphibians, and reptiles (O’Donnell et al. 2016). Human infections have been associated with several complexes of Fusarium species, although members of the F. solani (FSSC) and F. oxysporum (FOSC) species complexes are the most common opportunistic human pathogens (O’Donnell et al. 2010, Short et al. 2011, van Diepeningen et al. 2014).
