Morphology and life cycle
Nucleophaga grows within the nucleus of its host cell.[3] Its spores are ingested by the host and migrate to the nucleus. Once in the nucleus, the spores germinate giving rise to naked plasmodia in contact with the host's karyoplasm. It develops pseudopodia-like projections that may be involved in osmotrophy or phagocytosis. The Nucleophaga cells continue to enlarge until a cell wall replaces the projections and the Nucleophaga cytoplasm is divided into spores.[4]
