Ustilaginei
(named from Ustilago, the largest genus in the group). This is the scientific name of the Fungi included under the popular name of Smut, under which name is given a short account of them, and of the characters by which the more important genera are distinguished from one another. The mycelium seems to enter, usually, into seedling plants, and to make its way among the cells of all parts; but while the reproductive organs (spores) of some species may be formed in masses in almost any part of the host-plant, those of certain others are produced only in the reproductive organs (stamens or ovaries), or in the leaves. Several examples are mentioned under Smut. See also Ustilago.
