1. The organism previously known as Plasmodiophora vascularum Matz is transferred to the genus Ligniera Maire and Tison. 2. This organism lives primary in the tracheary tissues of the sugar cane but occasionally spreads to surrounding tissues. It does not cause hypertrophy of the host tissues. 3. It is the cause of a disease of sugar cane known locally as "dry top rot". 4. It is known only in Porto Rico and only in cane. 5. The life history is very similar to that of Plasmodiophora brassicae Wor. and to several species which have been placed in the genus Ligniera by Maire and Tison, Fron and Gaillat, Guyot, Schwartz and Winge.
