Introduction to the study of fungi : their organography, classification, and distribution for the use of collectors . Ramularia the mycelium is internal, and the conidiophores passin the same manner out into the atmosphere; but they areusually short, often unbranched, with a single conidium. InOidmm the myceUum is external, and the erect hyphae aresimple, but it is only the short lower portion which is truly acarpophore, for the upper portion is constricted successively,and the joints fall off as they are formed, and becomeconidia. There are also genera in which the carpophore is compound—that is to say, a number of threads are coml^ined so as to?form a common stem, which is consequently thicker and morepermanent. Either these individual hyphae diverge at theapex, or they remain united and form a capitulum, as in the combined threads form only a short erumpentstroma, as in Tuhercularia (Fig. 9), the carpophore is reducednearly to its lowest denomination, and is scarcely more thanan erumpent pustule. All the foregoing forms are repeated in Fl;. S.—Branched carpophore of 24 INTRODUCTION TO THE STUDY OF FUNGI the Dematioei, or black moulds, the chief difference being in thedark-coloured, more rigid, and carbonised hyphae. Eesembling the moulds in external habit, the Mucorsresemble them also in the carpophore, which is sometimesforked two or three times, but not dendritically branched. InPilobolus the carpophore is curiously inflated, like a bladder(Fig. 10). We have in remembrance a pseudo-analogy which some few years since became current—that the type of organisation in a Muce- dinous mould was repeated, with modifications, in the structure of , i_ _ ^ Agarics. The mycelium, it was con- IilH --^ f^ iL~ tended, was common to both. From the mycelium arose the carpophore, Fig. 9.—Compound carpophore which was a compound stalk, in of Tubercularia. -, . ?, --in which a myriad oi erect hyphaewere combined; in the pileus the combination was
