    Life History

    In the autumn, the mature fungal body falls to the ground, over-wintering in this state until late spring; when after a period of chilling, tiny pale pinkish or purplish drumstick-shaped fruit bodies develop from it producing thread-like asco-spores. These infect other grasses belonging to several genera including some of our most important food crops.
