A putrefactive anaerobe, C. flabelliferum n. sp., isolated from a table on which hams are handled in a large packing plant, is characterized by brush-like sporangia. It resembles C. sporogenes, but differs in manner of growth in broth and in the characteristic sporangia in the spore stage. This brush-like sporangium persists in egg-meat cultures for 2 months and clings to the spore long after spores of C. sporogenes have become free under the same cultural conditions.
