Verticillium endoparasite fruiting on dead nematode
The tiny spores of Verticillium have adhesive tips and bond to the cuticle of the nematode. A penetration peg grows through the epidermis of the victim and the fungus grows inside the body and eventually fills the host with hyphae. The fungus then breaks back out through the wall of the dead nematode for reproduction. Clusters of conidia are produced at the tips of elongate conidiogenous cells (phialides) arising in whorls from the conidiophores that radiate from the corpse. For more on Verticillium click here.
