This chapter discusses fungus that infects insects. The Cordyceps fungus, for instance, is capable of piercing the chitinous exoskeleton of insects. Although Cordyceps poses no threat to humans, its relative Claviceps is a source of great misery to us. Claviceps is the ergot fungus, a pathogen of rye whose toxins cause blood vessels to constrict so powerfully that hands and feet become gangrenous, causing patients to shed their nails and, eventually, their hands or feet. Saccharomyces cerevisiae, Ascobolus immerses, and lichens are also described.
