It can overwinter on leaves and fruits of Fragaria spp.

(Rosaceae), occasionally pathogenic on fruits causing strawberry stem-end rot.

The causal organism has often been referred to as Gnomonia comari, now considered Gnomoniopsis comari.

It occurs in Canada (British Columbia), Europe (Belgium, France) and U.S.A. (MD, NY).
