The fungi are traditionally classified according to the micro-anatomy of their fruiting bodies, the familiar mushrooms and toadstools. However there are some species that are only known to reproduce asexually and so never form a fruiting body, making it difficult to classify them. These include about 25,000 species and are often given the group name Deuteromycota or the Fungi Imperfecti. Members of this group may be assigned to their proper place in the classification system when more information becomes available.
