Revised scientific names of the genus Hemileia (Pucciniales) based on the new ICN Author Judith, Caroline Author Rossman, Amy text MycoKeys 2014 8 1 10 http://dx.doi.org/10.3897/mycokeys.8.4040 journal article http://dx.doi.org/10.3897/mycokeys.8.4040 1314-4049-8-1 Hemileia mussaendae Vienn.-Bourg., Bull. Soc. Mycol. France 67: 431, 1951. = Hemileia pieningii Deighton, Trans. Brit. Mycol. Soc. 55: 497, 1970. [= Hemileia mussaendae Cummins, Bull. Torrey Bot. Club. 87: 36, 1960 non Vienn.-Bourg. 1951, hom. illeg. non Vienn.-Bourg. 1951] Comments. Hemileia mussaendae Vienn.-Bourg. was the first name published for this species. Because the type specimen lacked teliospores, Cummins (1960) established a new name using another type specimen. Because Cummins' (1960) name is a later homonym of Hemileia mussaendae Vienn.-Bourg., Deighton (1970) provided a new name based on the same type specimen. With the new ICN, the oldest epithet has priority.
