Cycloheximide Sensitivity as a Taxonomic Character in Ceratocystis

Abstract

SUMMARYThe effect of 100 ppm cycloheximide on the linear growth of 53 species of Ceratocystis sensu amplo and related fungi was determined on malt extract agar at 25 C. Generally, only those species with Chalara-like anamorphs (Ceratocystis sensu strıcto) were inhibited by 100 ppm cycloheximide. Growth of other Ceratocystis species (Ophiostoma sensu von Arx), Europhium spp., and related anamorphs was generally unaffected by cycloheximide.
