Abstract
SUMMARY Two new saprophytic species of Aphanomycopsis, A. saprophyticusand A. punctatus, from Oceania soils are characterized by extensive, branched, occasionally septate mycelia, undifferentiated cylindrical, simple or branched sporangia, primary zoospores which glide out of the sporangia and encyst at the exit orifice as in Aphanomyces, motile diplanetic secondary zoospores, and by asexual resting spores which develop in swellings or vesicles in the mycelia. The genus Aphanomycopsis is emended to include such species and placed in the family Saprolegniaceae near Aphanomyces.
