The production of ornamental plants in Mexico represents a job-generating activity that has grown in recent years; however, it is adversely affected by phytosanitary issues, notably those induced by . Studies of in ornamental nurseries are scarce in Mexico. The aim in this study was to identify species from selected ornamental plant nurseries in Mexico as potential new hosts. Samples of 13 genera diseased plant tissue and soil were collected from eight nurseries in Mexico during 2009-2010. Based on morphology and sequences of ITS rDNA, the 19 isolates obtained were identified as , , , , , , and . Additional loci were sequenced to support species determinations within the species complex; some of these isolates could not be confirmed as belonging to any described species, and one appeared to be an interspecific hybrid. This is the first report of in Mexico; this is noteworthy due to being a broad host range, similar to most of the other species encountered. Evidence of nursery-grown plants serving as a vector to a home garden has been reported for the first time in Mexico. and are new hosts for worldwide.
