Albuginaceae

The fungus develops within the plant , feeding by means of haustoria: tiny protuberances that by means of small openings penetrate a cell . Below the plant’s epidermis a layer of hyphae endinds is formed, that each produce a chain of conidia, resulting in a shining white crust. Finaly the epidermis ruptures, releasing the conidia. These germinate into motile spores, that can infect a new host. Because of their biological function the conidia are alternatively called “conidia” and “sporangia” in the literature.
