Preliminary findings on <i>Clarireedia</i> species associated with dollar spot in turfgrass in Spain

Abstract Dollar spot is one of the most destructive diseases affecting turfgrass worldwide, impacting both warm‐ and cool‐season species. The causal agents were recently reclassified into a new genus, Clarireedia spp., with six species currently described. In this study, symptomatic plant samples were collected from C3 ( Poa annua ) and C4 ( Paspalum vaginatum ) turfgrass species from two golf courses in Spain and identified to species level based on the internal transcribed spacer region. Three isolates from C3 species were identified as Clarireedia jacksonii and three isolates from C4 species were identified as Clarireedia monteithiana . To our knowledge, this is the first report of C. monteithiana isolated from symptomatic turfgrass in Spain; however, pathogenicity tests are required to confirm the pathogenicity of these isolates.
