In the higher Fungi nuclear fusions take place in basidia or asci which involve the union of two (fig.
Ascophorous, producing asci; ascospore, the spore (or sporule) developed in the ascus; ascogonium, the organ producing it, &c.
Fructification of the fungus, entire and in section; the latter shows the asci containing ascospores, much enlarged.
The hypothecium is the basal part of the apothecium on which the hymenium is borne; the latter consists of asci (thecae) with ascospores, and paraphyses.
As indicated above, the weight of evidence seems to favour what has been put forward in the case of the non-lichenforming fungi (see Fungi), that in some cases the ascogonia develop as a result of a previous fertilization by spermatia, in other cases the ascogonia develop without such a union, while in still other Epithecium Asci :Thecium (Hymenium) Paraphyses Parathecium, - Cortex gn,go mphitheciam - __ __MeddllzC-- _Hypoitienum==?=_` After Darbishire, from Berichte der deutschen botanischen Gesellschaft, by permission of Borntraeger & Co.
