Maximum Likelihood phylogenetic tree depicting the position of the two Knoxdaviesia species sampled from Protea repens infructescences. The final dataset consists of 474 characters. Knoxdaviesia proteae sequences are from the studies of Aylward et al. (2014a, 2015) and K. capensis sequences were generated in this study. “T” and “ET” indicate type and ex-type strains, respectively.
