Epichloë coenophiala

Epichloë coenophiala (Morgan-Jones & Gams) Bacon & Schardl, 2014

on Schedonorus


The fungus is systemic and fully asexual – no fruiting bodies are produced. The nest grass generation becomes infected because the mycelium invades also the developing seeds. The fungus defends its host by the production of toxic alkaloids, that can result in extensive cattle mortality (“fescue toxicosis”).
