The broad, expanded cap or pilius bears the gills on its lower surface and is supported by the stalk or stipe. The young fructifica- tion, at left, is surrounded by a membrane or volva, which breaks as the pileus expands, and the remains of which can be seen as a ring around the stipe. pine blister rust, which has its uredo-stage on currants and gooseberries; the apple rust, which has its teleuto-stagc on red cedar, and many others. The typical or true Basidiomycetes, or Autohasidiomycetes, include two main sub-classes; the Hymenomycetes, in which the fruiting surface or hymcnium is exposed to the air, and the Gasteromycetes, in which it is enclosed within the tissue of the.
