Hemileia rhois E. Castell., Nuovo Giron. Bot. Ital., new ser. 49: 20, 1942.

= Hemileia castellanii Ritschel, Bibl. Mycol. 200: 21, 2005.

Comments.

Because Hemileia rhois is based on urediniospores, Ritschel (2005) published a new name for this species based on a type specimen with teliospores. With the new ICN, the correct name based on the rules of priority is the oldest one.
