Epichloë

Epichloë coenophiala hyphae between tall fescue leaf cells
N-formylloline, an insecticidal alkaloid produced in several Neotyphodium–grass symbiota.

Epichloë is a genus of ascomycete fungi forming an endophytic symbiosis with grasses. Grass choke disease is a symptom in grasses induced by some Epichloë species, which form spore-bearing mats (stromata) on tillers and suppress the development of their host plant's inflorescence. For most of their life cycle however, Epichloë grow in the intercellular space of stems, leaves, inflorescences, and seeds of the grass plant without incurring symptoms of disease. They provide in fact several benefits to their host, including the production of different herbivore-deterring alkaloids, increased stress resistance, and growth promotion.
