Elsinoë in Uganda

Abstract

Uganda has proved a rich collecting ground for species of Elsinoe (4) as shown by Hansford's (3) description of seven new species from that region, together with mention of several other species also found there. Among the latter group are E. Canvaliae Rac.? on Dolichos lablab, recently described as a distinct species, E. Dolichi, by Jenkins, Bitancourt and Cheo (5), E. Fawcetti Bitancourt and Jenkins (1) on Citrus, and E. Tephrosiae Hansford (2) on Tephrosia candida. The new species described are E. Piperis on Piper capense (Piperaceae) ; E. Adeniae, E. antiaridis and E. Urerae on Adenia sp., Antiaridis toxicaria, and Urera camerunense, respectively, of the Urticaceae; E. Pseudospondiadis on Pseudospondias microcarpa (Anacardiaceae), E. Tylophorae on Tylophora sp. (Asclepidaceae) and E. Chandleri on Mikania scandens (Compositae). In addition Elsinoe sp. is reported on Stereospermum kunthianum. Specimens of these seven new species with the exception of E. Tylophorae were contributed to the writers by Hansford before the descriptions were published and they are filed in the Mycological Collections of the Bureau of Plant Industry and in the Secqao Fitopatologia, Instituto Biologico, Sao Paulo, Brazil. Upon discovering still another species of Elsinoe in Uganda in September 1940, Hansford sent an ample gathering of this to the writers with the request that they prepare the diagnosis. In recognition of Hansford's notable discoveries of fungi of this pathogenic group in Uganda this species will be designated in his honor. The description follows:
