The mycelia of several sterol-producing and non-sterol-producing fungi were analyzed for the presence of squalene, squalene epoxide, lanosterol, and ergosterol. The sterol-producing fungi contained all four compounds, whereas only squalene was detected in the non-sterol-producing fungi. The block in the synthesis of ergosterol by the latter organisms is presumed to occur at the stage at which squalene is usually oxidized to squalene epoxide.
