Persimmon (Diospyros kaki) anthracnose is a major threat in production areas worldwide. Most of the studies are focused on Colletotrichum horii, but other species have been reported as well. The association of distinct Colletotrichum species present in Brazilian persimmon production regions as well as their host ranges are yet elusive. The aims of this work were to identify and characterize Colletotrichum species associated with the persimmon anthracnose. In a survey performed in four production regions of Brazil, 88.7% and 11.3% out of 231 isolates were identified as members of Colletotrichum gloeosporioides species complex (Cgc) or Colletotrichum acutatum species complex (Cac), respectively. A subset of 18 isolates were identified through multilocus phylogenetic analysis, using ITS-rDNA region and two loci, namely GAPDH and TUB2. This study revealed the presence of four species: C. horii (38.8%) and Colletotrichum fructicola (27.7%) from the Cgc and Colletotrichum nymphaeae (27.7%) and Colletotrichum melonis (5.8%), from the Cac. Additionally, 13 isolates were selected for morphological, physiological, and pathogenic analyses. Contrasting characteristics were observed among species of the Cgc and Cac complexes. The optimal temperature for mycelial growth and germination were higher for Cgc species. The percentage of appressoria melanisation also varied across complexes. All the identified species were able to cause anthracnose-like symptoms on persimmon fruit, leaves, shoots, and sepals. Colletotrichum species from persimmon were also able to infect apple and pear. The findings will support decisions to manage anthracnose of persimmon under high infection risk due to multiple host susceptibility.
