Abstract
In Spiniger meineckellus erect, hyaline conidiophores arise from the mycelium; as they elongate, they expand at the apex to form an ampulla. Bulges occur over the surface of the ampulla as denticle formation begins. Initially, all four layers of the ampullar wall push outward, but soon the two outermost wall layers rupture, exposing the electron-opaque, third wall layer. This layer, along with the thin innermost layer, pushes out and forms the wall of both the denticle and of the single conidium which develops holoblastically at its tip. This appears to be the only botryose species in which rupture of the ampullar wall during denticle development has been confirmed. Whether this is related to the fact that it has a basidiomy
