The perithecium develops gradu- ally from spirally coiled h}^hae. The hyphae of the screw are divided. Fig. 49.—Aspergillus oryza associated with yeasts in the making of the Japanese beverage Sake. Vegetative hiTihae (a) and spore-forming hyphae (6, c, d) are shown. Fig. 71, p. 152. [Schneider, Pkarmacetilical Bacteriology, 1912, 19.) transversely into as many cells as there are turns of the screw. The bottom hyphal cells of the screw send up two or three branches of irregular thickness which grow toward the apex. One of these branches looked upon as an antheridium grows more rapidly than the others and its contents serve to impregnate the inclosed carpogone. These outer erect hj^jhae then branch copiously to completely envelope the carpo- gone and the perithecial wall is thus formed. From the carpogone are now formed the numerous ascogenous hApha", which branch plenti-.
