It is recommended that the generic name Aspidelia and the species name Lichen quisquiliaris not be rejected under Art. 56. The following two species names are recommended for rejection under Art. 56: Botrytis farinosa (Peronospora farinosa) and Saccharomyces sphaericus. As a result of reference under Art. 53.5, it is recommended that the following two pairs of names are not to be treated as homonyms: Bertia De Not. and Bertya Planch.; and Otidea (Pers.)
