CHAPTER V.—COMPARATIVE REVIEW ASCOMYCETES.—PYRONEMA. 209 embraces its apex and presses its obtuse extremity firmly against it. When this has taken place, seldom before, the tube is delimited by a firm transverse wall from the inflated portion of the archicarp, and, as soon as the wall is formed, the membrane in each of the connected organs is dissolved at the point of contact of the tube with the antheridium, and the protoplasmic bodies of the two organs unite together through a broad aperture (Fig. 97 B). The bent tube is therefore an organ which affects an. Fig. 97. FICS. 96—99. Pyronema anifiuetis, TuL Fig. 96.
