Nucleophaga grows within the
nucleus of its host cell. 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. ==Taxonomy==
