The lower part of the cup is filled by the hypo-thecium, a tangle of hyphae, some vegetative, some ascogenous. Thesegive rise to the sub-hymenial layer where the paraphyses have their originand where the young asci are developed. The asci and paraphyses grow uptogether and rise to the surface of the ascocarp forming the hymenium orfertile disc which is spread over the interior of the cup. The asci are moreor less cylindrical and parallel one to another and to the paraphyses (fig. 53).They open either by a lid (fig. 55) or by the ejection of a plui; (fig. 54).They arise in succession so that large numbers may be produced in a singleascocarp.
