Fungi. 58 INTRODUCTION TO THE STUDY OF FUNGI vital energy, which is immediately applied to the production of the filamentous tissue on which the disc is- later to be borne. Tulasne found the scolecite readily in Ascobolus furfuraceus, but failed in tracing fertilisation; but he was rather more successful with Pyronema melaloma, in which he found that the scolecite is certainly a lateral branch of the mycelium (Fig. 35). This branch is simple, or forked at a short distance from the base, and its diameter gen- erally exceeds that of the filamentwhich bears it. It is soon bent and often elongated in de- scribing a spiral, the irregular turns of which are lax or compressed. At the same time its cavity is divided into eight or ten cavities. Sometimes he had seen this special branch terminated by a crosier, and interlocked with the bent part of an analogous crosier terminating a neighbouring filament. In other cases the growing branch was connected by its extremity with that of a hooked branch. These contacts, therefore, seemed rather accidental than constant. There was, however, no room to doubt that the scolecite was the habitual rudiment of the fertile cup. The most complete observations were those on Pyronema omphalodes. The globose vesicles, or macrocysts, which are the beginning of the fertile tissues—each of them emits from its apex a cylindrical tube, always more or less bent in a crosier shape, so that the vesicles resemble so many tun-bellied, narrow-necked retorts filled with a roseate plasma. Out of the same filaments are produced elongated clavate -cells, named paracysts, which soon exceed the macrocysts in height,. Fig. 35.—Scolecite.
