In Phyllactinia Corylea and also in Microsphaera ^/«? (Sands, 1907) and various species of Erysiphe (Harper, 1905), the organization of the resting nucleus is very characteristic. A deeply staining central body lies against the nuclear membrane and to this the chromatin threads are attached. From it they extend into the central cavity of the nucleus forming a sheaf of divergent rays connected laterally by delicate fibrillae (fig. 46)..
