Correction to: Nature Ecology & Evolution https://doi.org/10.1038/s41559-020-1221-7, published online 22 June 2020.

In the Supplementary Information for this Article originally published, in the ‘Diagnoses_Prasinodermophyta’ file of Supplementary Data 1, Pyramimonadophyceae was described as a new class. However, this class was previously described in an article by Daugbjerg et al.1 and thus the description was removed.

Additionally, this file was originally presented in Word format, but according to Articles 29.1 and 29.3 of the ‘International Code of Nomenclature for algae, fungi, and plants’2, the nomenclatural acts were thus not effectively published because they were not presented in a portable document format (PDF). To effectively publish the nomenclatural novelties, the file has now been provided as a PDF file titled ‘Diagnoses_Prasinodermophyta_corrected’.

These errors have now been corrected.
