By means of the freeze‐etching technique ultrastructural alterations in Saccharomyces cerevisiae cells undergoing autolysis at elevated temperature were studied. Wall surfaces of intact cells were smooth. During autolysis wall surfaces became rough with granules of 20–40 nm diameter. This alteration occurred after extensive disintegration of cytoplasmic organelles and after functional and ultrastructural impairments of the plasma membrane, but well before the rupture of the plasma membrane.
