Dieback of red currant ( Ribes rubrum ) and gooseberry ( Ribes uva-crispa ) is an increasing problem in commercial fields in the Netherlands. Field surveys were done in 2006–2007 and samples with dieback symptoms were analysed. In this study the causal agent was diagnosed as Eutypa lata , based on morphological characteristics and rDNA-ITS sequence data. The field surveys revealed the presence of the anamorph and teleomorph states of the fungus produced on dead infected currant wood. Eutypa lata is a vascular pathogen of many woody plants. Related fungi from the same family Diatrypaceae are difficult to distinguish from E. lata based on morphological features. The genetic variability of E. lata was compared by rDNA-ITS sequencing of isolates from different hosts and origins. Within the E. lata isolates little variability in the ITS sequences was observed. Phylogenetic analysis showed no clear subdivisions within the species. Eutypa lata strains isolated from the different hosts were closely related, indicating that there is no direct evidence for host specificity.
