This species occurred in great abundance and caused swellings of the hyphal tips and incipient sporangia which were up to 80 um in diameter. Unfortunately, no resting spores were developed by the New Zealand parasites. Until these are found it is impossible to classify this species. It is recorded and discussed here in relation to the Olpidiopsidaceae only because it produces biflagellate zoospores. Otherwise, the development of other species in relation to the host and the types of sporangia and resting spores produced are similar to those of Rozella in the chytrid family Olpidiaceae.
