Abstract
A medium containing linoleic acid, cycloheximide, dicloran, triphenyltin hydroxide, chloramphenicol and streptomycin sulfate in potato-dextrose agar was developed for selective isolation of C. ulmi. The medium facilitated the rapid isolation of C. ulmi from elm tissue and bark beetles [Scolytus multistriatus]. An aggressive isolate of C. ulmi retained pathogenicity after being cultured on the medium, and all isolates of the fungus tested grew on the medium. A strain of C. montia, causal agent of blue stain of conifers, also grew on the selective medium. C. montia, like C. ulmi, forms conidia exogenously; C. fimbriata and C. fagacearum, 2 spp. that form conidia endogenously, did not grow on the medium.
