Abstract

In the fall of 1935 a number of specimens of seedlings of Robinia pseudo-acacia L. were submitted to the Department of Botany of Iowa State College for the investigation of a canker which was girdling the sterns of these plants at or about the ground line. On a majority of the specimens examined, the injury consisted of a sunken area approximately two centimeters in length completely surrounding the stem. The wood under these cankers was materially browned and the cambium was dead. Many of these cankers were covered with orange sporodochia of a fungus which microscopic examination proved to be a member of the genus Fusarium. A survey of the extent of the disease was made and the identity of the fungus and its relationship as a possible factor in the causation of the canker was investigated.
