Eutypa lata is the most common diatrypaceous fungus in grapevine cankers. This study was undertaken to determine the presence and diversity of other members of the Diatrypaceae in grapevines in California. We isolated into pure culture 11 species of Diatrypaceae from the wood of diseased grapeviens including Cryptosphaeria pullmanensis, Cryptovalsa ampelina, Diatrype oregonensis, D. stigma, D. whitmanensis, Diatrype sp., Diatrypella verrucaeformis and four species of Eutypella. Species were identified or grouped morphologically and by phylogenetic analyses of the complet-e sequence of the internal transcribed spacer (ITS) of the rDNA and beta-tubulin gene. Diatrypaceous fungi also occurred frequently on the native flora surrounding vineyards, thus serving as possible inoculum sources for these putative pathogens.
