Abstract
The surface and cavity of the perithecium of Ceratocystis stenoceras were studied with a scanning electron microscope.
The body was spherical, 96–231 μ 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 near 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 × 2 μ with smooth surface.
