Young spherules (adiaspores) of the fungusEmmonsia crescens from the cultures growing on Sabouraud's dextrose agar have been prepared for electron microscopy by the technique of freeze-etching. In the cytoplasmic membrane grooved invaginations corresponding with the ridges on the inner face of the cell membrane have been found. The surface of the cytoplasmic membrane is densely covered with regular globules, the diameter of which is about 100 A. Mitochondria, endoplasmic reticulum, nuclear membrane with pores, and numerous stock materials in the form of fatty drops, and glycogen can be identified in the cytoplasm.
