Agaricus bisporus
"Rhopalomyces elegans" can itself be parasitized by the fungi "Mycogone perniciosa" and "Verticillium psalliotae". "Verticillium psalliotae" is a saprobic soil-dwelling fungus that is a parasite of the common commercially grown button mushroom ("Agaricus bisporus"). "R. elegans" may serve as a reservoir for the pathogen, and may harbor the parasite in its thick cell walls.
