Braun et al., Polish Botanical Journal 55(2): 281-291, 2010. “This is the first record of a Cercospora species on Helmholtzia and a host of the Philydraceae in general (Crous & Braun 2003). The morphology agrees well with the C. apii complex as defined by Crous and Braun (2003)…. Following the advice of Crous and Braun (2003), this collection is assigned to C. apii s.l. since no cultures, molecular sequence analyses or results of inoculation tests are available”
