choke of grasses A disease that can affect many types of grass, particularly cocksfoot (Dactylis glomerata) and timothy (Phleum pratense). The causal agent is the fungus Epichloë typhina. A ring of white, felt-like mycelium develops around the flower stalk and becomes yellow, then orange, as the fungal perithecia develop. Flowering is partially or completely suppressed.
