In the above mentioned publication, the new combinations Chrysosporum ovalisporum (Forti) comb. nov. and Dolichospermum tenericaule comb. nov. were invalid, as the names of the basionyms and the pages of related publications were not cited in accordance with the requirements of Article 41.5 of the International Code of Nomenclature for Algae, Fungi and Plants (McNeill et al., 2012).

The authors regret this mistake and therefore validate these combinations as follows:
