ThusDangeard describes the oogonium as undergoing septation before it branches,while Barker interprets the mass of protoplasm in which the young asci arefound as the remains of the oogonium invaginated by the growth into it ofthe ascogenous hyphae. Kuyper and Ikeno, on similar grounds, believedthe asci to be produced by free cell formation within the oogonium, noascogenous hyphae being 35.
