Introduction to the study of fungi : their organography, classification, and distribution for the use of collectors . Fig. 35.—Scolecite. After De Bary. FERTILISA TION 59 and seem to carry their summit so as to meet the crosier-shaped appendages, and they are soon united two and union or meeting of the extremity of the crosier tubewith the neighbouring paracyst was a constant fact, which hehad observed a hundred times, and leisurely during a fewmonths. There is no joining of these cells except in the verylimited point where they meet, and there may be seen acircular perforation at the end, defined by a round they may be very near together, but they arealways free from any adherence whatever.

After De Bary. affirmed—that the conjugated cells, especially the larger,wither and empty themselves, while the upright tubes, whichultimately constitute the asci, increase and multiply. As to the scolecite, so called, there can be no doubtthat some such bodies have been seen, but their significancehas been misinterpreted. It is probably the first distinctionof the fertile from the sterile hyphae, and in no senserepresents the female organ. The above will suffice for the Ascomycetes; and we haveleft to us the Phycomycetes, as containing the most decided anddefinite examples of sexuality amongst the Fungi. The Mucors,in species already investigated, develop zygospores from thehyphae of the mycelium (Fig. 36). A short clavate branchis produced from each of two neighbouring hyphae. Thesebranches approach each other by their apices until they touch,and are called the suspenders. They contain an abundance of 6o INTRODUCTION TO THE STUDY OF F
