✦ Synopsis

The surface and cavity of the perithecium of Ceratocystic stenoceras were studied with a scanning electron microscope. The body was spherical, 96-231 u in diameter, and the surface was covered with hyphae. The neck was a lanky hollow cylinder and the wall consisted of a bundle of tubular hyphae encircling a central canal. A whorl of hyaline hyphae was found at the tip of the neck. The surface of the neck from the body to a distance of about 1/6 was rough and warty. But the surface of the neck above that place was smooth, on which a regular design could be seen. The wall of the neck the body consisted of 5-6 layers of cells. However, the wall at the tip was of 1-2 layers of cells. The cavity was filled with ascospores. They were like segments of an orange of 1 X 2 u with smooth surface.
