The Homobasidiomycetes comprises those Basidiomycetes characterized by simple basidia and basidiospores which do not, as a rule, germinate by repetition but produce a mycelium directly. According to the current treatment followed in this laboratory, there are seven recognized orders, all of which occur in Iowa. One order, the Exobasidiales, is characterized by the absence of a fruiting body, the place of that structure being taken by the parasitized tissues of the host. Of those orders in which a basidiocarp is present, the Agaricales possesses a hymenium or fruiting layer often exposed from the beginning and always before the spores are mature. When one thinks of fungi, one usually thinks of members of this order. The Agaricales may be divided into six families. Any key to such a group is by nature artificial, but such division seems to be reasonably usable.
