lolitrem-b

Description: Lolitrem B is a naturally occuring toxin found in a fungus called Epichloë festucae (var. lolii), which grows in perennial ryegrass. The fungus is symbiotic with the ryegrass; it doesn't harm the plant, and the toxins it produces kill insects that feed on ryegrass. Lolitrem B is one of these toxins, but it is also harmful to mammals.
