The thin walled sporangia release diploid zoospores. Asexual reproduction involves the formation of chlamydospores and sporangia, producing motile zoospores. The sporangia release zoospores that infect other cells. It has two morphologic forms&colon; filamentous hyphae and motile zoospores. Alternatively the sporangia can create and release up to 14 flagellated zoospores. Most oomycetes produce self-motile zoospores with two flagella. Trophozoites in the water mature and release flagellated zoospores. The second stage takes place when the initial asexual zoosporangia produce motile zoospores. In the spring, resting spores in the soil germinate and produce zoospores. Instead, PiCdc14 is made during the formation of asexual spores, including its biflagellated zoospores. These indirectly germinate and release zoospores. Asexual reproduction occurs through the release of zoospores (presumably) derived through mitosis. Inoperculate chytrids release their zoospores through pores, slits, or papillae. In the spring, oospores germinate to produce macrosporangia, which under wet condition release zoospores. The fungus grows on amphibian skin and produces aquatic zoospores.
