It forms xenoparasitic complexes of the cell-hypertrophy tumour type, and is found in the gills of the Atlantic cod Gadus morhua. It is apansporoblastic, unikaryotic, disporoblastic and undergoes partial development in parasitophorous vacuoles, while lacking plasmodial stages. It produces one or two spores in a vacuole, having tubules in the parasitophorous vacuoles.
