The pre–penetration and post–penetration stages of infection by Cladosporium allii–cepae on onion foliage was examined on inoculated plants kept at 15° C and 80–90% r.h. The pathogen entered the leaf usually through stomata but occasionally by penetrating the cuticle. Invasion of the palisade and mesophyll tissues led to the formation of a leaf cavity after 7 days and after 30 days the pathogen sporulated on the leaf surface.
