Buhr additionally cites “Ustilago bromi-secalini Voss & von Thümen”; neither the Index Fungorum nor Vánky know this species, most probably another synonym of bullata.

According to Klenke & Scholler bromivora is the valid name, and bullata a synonym; however, here the Index Fungorum (2016) followed.
