Introduction to the study of fungi, their organography, classification, and distribution for the use of collectors . withinan indehiscent peridium ; but they differ in the spores beingenclosed within asci, instead of being produced on basidia, andin this respect are allied to the Pyrenomycdes. In so far as their final, and reproductive, stage is concerned,the Myxomycetes resemble the Gastromycetes; they are some-times stipitate, possess a distinct peridivim, in which the sporesare enclosed until maturity, and the latter are mostly coloured,globose, sometimes rough, mixed with the threads of acapillitium. On the other hand, the early or vegetative stageis so different, that the ancient notion of their affinity mustbe abandoned, although they are entitled to mention in thisplace as Fungi which produce their fructification enclosedwithin a peridium. Notwithstanding this, thei*e are those whoregard it as heresy to mention the Myxomycetes on the samepage as the Gastromycdcs. The fructification, which is produced witliin an open cup-is of more than one kind, but the mostimportant is that of shaped excipuh. 6—/ Fig. 24.—Section of hyiuenium iu Peziza. the Discomycetes, inwhich the spores areascomycetous — that isto say, they are pro-duced within asci. Indescribing the recep-tacles it was stated thatthe fructiferous surfacewas a compact stratumor hymenium, whichoverspread the interior of the expanded receptacle. In thisinstance the fruit-bearing surface is superior, and soon fullyexposed to the light. It is plane or slightly convex when moist,depressed and concave when dry, from the contraction of thereceptacle,and often brightly coloured (Fig. 24). The hymenium,or disc, is composed of elongated cylindrical or clavate cells,which are formed of a delicate hyaline membrane, splitting atthe apex, or opening with an operculum. These cylindricalcells are closely packed side l:)y side and constitute the asci, THE FRUCTIFICATION 45 which are generally mixed with slender th
