sentences:  Sclerotia are hard resting structures that later (after incubation on the ground) germinate to form stipate stromata.Depending on the fungus species, the host tissues on which stromata or sclerotia are produced may be young inflorescences and surrounding leaves, individual florets, nodes, or small segments of the leaves.Young stromata are hyaline (colorless), and as they mature they turn dark gray, black, or yellow-orange.
