Parasitella

Parasitella is a genus of fungi belonging to the order Mucorales. These fungi are characterized by their obligate parasitic nature, meaning they cannot survive without a host. The type species, Parasitella simplex, is a well-known example and was first described in 1881. Parasitella species are typically found parasitizing other fungi, particularly those within the Mucorales order itself, a phenomenon known as mycophagy. Their reproductive structures, known as sporangia, are small and contain numerous spores. These spores are released and dispersed, seeking out new fungal hosts to infect. The parasitic relationship often leads to the demise or significant weakening of the host fungus. Research into Parasitella has contributed to understanding inter-fungal parasitic interactions and the ecological roles these organisms play in decomposition and nutrient cycling within soil and decaying organic matter. While not directly harmful to humans or animals, their parasitic lifestyle on other fungi makes them of interest in mycology and ecological studies. The genus is relatively small, with only a few recognized species.
