Soybean ( Glycine max ) can be infected by many different Diaporthe species; among them, D. caulivora and D. longicolla are responsible for the most significant damages. Diaporthe goulteri is a species that was only recently described and has so far been found on sunflower ( Helianthus annuus ) in Australia and an unknown host in Thailand. Here, we report isolation of D. goulteri from soybean in southern Germany, molecular species identification, and additional morphological description. We also show that D. goulteri can infect soybean and describe the symptoms we observed, both on the plant where the isolate came from and following artificial inoculation.engIsolationSpecies identificationPhylogenyMorphologyPathogenicity630Article2025-11-28
