Colony morphology was documented from cultures growing on V8 PARP plates.
For light microscopy of sporangia and gametangia, agar cubes were aseptically removed from the leading edge of agar colonies and incubated in 15 ml of halfstrength seawater (13 ‰ salinity) or distilled water in Petri
dishes for 5–10 d.
Sporangia and oospores were photographed and measured using a Nikon Eclipse 80i microscope, and the Nikon NIS-Elements v2.2 digital imaging software.
