At the same time an abundant growth of hy- phae takes place from the mycelium below the car- pogonium, and from this the greater part of the mass of the fruiting plant is produced; it also invests the hyme- nium, forming the so- called i^ericarp which encloses it (r. Fig. 197). Yerticai branches of the sterile tissue also pass into the hymenial layer and constitute the paraphyses. 381.—The asexual reproductive bodies are but little known, but enough is known to indicate that there is at least a conidi.'i-bearing stage for these Ascomycetes, as for all others. De Bary has shown that the early stage of the little plant known as Peziza FucJcelimia is mould-like in appear- ance, in fact having been described as a mould under the name of Polyactis cinerea. In this stage it grows upon dead grape leaves, sending its mycelium through the dead tissues. Its vertical hyph^ produce clusters of oval conidia, which are much like those produced in the correspondin.
