Fruiting Bodies
The fruiting body in
Pyronema is the apothecium. Other fruiting bodies occur
in other species. In some species, the fruiting body containing the asci and
the paraphyses may be entirely closed. This is called a
cleistothecium and is
shown in figure 19-4a. In one genus,
Exoascus, there is no evident fruiting
body. Rather, the asci and paraphyses develop on an open surface. A fruiting
body that is nearly but not quite enclosed is called a
perithecium (figure 19-4b).
