A recent publication has documented the fact that when the nomenclatural types of the genera Zhang . 2018 [ (Viljoen . 1926) Zhang . 2018], Patel . 1980 ( Patel . 1980) and Koeck . 2016 ( Koeck . 2016) are treated as being members of the same genus, i.e. Zhang . 2018, Patel . 1980 and Koeck . 2016 are treated as heterotypic synonyms, the name at the rank of genus to be used is Patel . 1980 and Zhang . 2018 is an illegitimate name. In a previous publication this led to the replacement of the genus name Zhang . 2018 in the combinations (Yang . 1990) Zhang . 2018, (Zhilina . 2006) Zhang . 2018, clariflavum (Shiratori . 2009) Zhang . 2018, (Kato . 2004) Zhang . 2018, saccincola (Koeck . 2016) Zhang . 2018, (Patel . 1980) Zhang . 2018 and (Viljoen . 1926) Zhang . 2018. Given the fact that the name Zhang . 2018 is illegitimate, Rettenmaier . 2019 must follow the same fate as other members of the genus and the illegitimate genus name replaced by the genus name Patel . 1980, creating the combination (Rettenmaier . 2019).
