Abstract
Mesochytrium penetrans gen. et sp. nov. is an obligate parasite of the green alga Chlorococcum minutum. Spherical zoospores with a posterior flagellum contain a rumposome, microtubule roots, and a single lipid globule. Ribosomes are concentrated around the nucleus and form an ill-defined ribosome aggregate. The pyriform zoosporangium partly penetrates the host cell; zoospores escape through a single wide apical opening. The empty sporangium has a goblet-like shape, it lies partly inside the algal cell wall. Delicately branched rhizoids arise from a sole main axis on the base of the sporangium. Resting spherical spores are endobiotic; their wall is thick and smooth.
