Abstract

First report of Colletotrichum acutatum sensu lato through the occurrence of C. godetiae on cornelian cherry (Cornus mas) in Europe.

Abstract

In September 2011, anthracnose symptoms were noticed on fruits of cornelian cherry (Cornus mas) in Bársonyos, Hungary. Brown, shriveled, sunken spots appeared on the surface of ripening fruits, with orange conidial masses within the spots. Conidia present in acervuli were colorless, fusiform, and 16.94 to 29.07 µm (average 23.08) × 5.25 to 11.33 µm (average 8.05) (n=100). Based on morphological characteristics, polymerase chain reaction and pathogenicity tests, the causal agent was identified as Colletotrichum godetiae, a member of the Colletotrichum acutatum species complex. Symptoms similar to those of this first report were also observed on this host in Iran and the causal agent was identified as Colletotrichum acutatum. This is thought to be the first report of Colletotrichum acutatum sensu lato on cornelian cherry fruits in Hungary and in Europe through the first occurrence of Colletotrichum godetiae on this host.
