They are distinguished by the fact that Rhyparobius produces several large asci, and Thelebolus only one (fig. 83). In both genera the cells of the mycelium are uninucleate. In Rhyparobius {Thecotheus) Pelletieri Overton has described several. Please note that these images ar

THE FUNGI WHICH CAUSE PLANT DISEASE 117 The oogonium after fertilization gives rise to a more or less complicated system of ascogenous hyphae, very simple in the Erysiphaceae, very complex in some Discomycetes, which produces the asci. The sterile parts of the ascocarp, the paraphyses and enveloping structures, arise from parts below the oogonium and antheridium. The very young ascus usually receives two nuclei from the parent strand of the ascogenous hypha. These nuclei unite giving the. Please note that these images are extracted

CHAPTER V PYRENOMYCETES The Pyrenomycetes include some 10,000 species; they are characterized by the fact that their ascocarp or perithecium is a more or less flask-shaped organ opening by a narrow pore, the ostiole, and containing a hymenium spread in a regular manner over the floor and lower part ofthesides (fig. 100). It thus differs from the perithecium of the higher Plectascales where the asci are irregularly scat- tered, and from that of the Erysiphales where, except in the flattened perithecium of the Microthyriaceae, an ostiole is
