Sporangia were produced by transferring agar plugs (10̉10 mm2) from actively growing area of 10-day-old cultures on CV8A to Petri dishes containing non-sterile, 1.5% soil water extract solution (SWE, 15g of sandy loam soil/1 L distilled water) or filtered, non-sterile pond water. Mature sporangia developed after incubating at room temperature (c. 23̡C) under cool-white fluorescent light. Sporangia and gametangia were photographed with a Nikon Fujix Digital Camera HC-300Zi connected to a Nikon Labophot-2 microscope. Fifty randomly selected mature sporangia were measured for length and width while 30 gametangia were measured for the size of oogonia, oospores, and antheridia with Image-Prǫ Plus v. 5.1.2.53.
