摘要

A newChytridiumspecies,C. deltanum, is described growing onOocystis crassa, O. lacustris, O. submarina, andO. parva. A sexual process is involved in the formation of the endobiotic resting spores. The occurrence ofChytridium oocystidisHuber-Pestalozzi onO. lacustrisandO. crassais briefly described. Three other fungi as yet not completely identified, but evidently new to science, are described onOocystisspp. One of these appears to be aLagenidiumspecies.
