The freely extractable sterols of spores of Linderina pennispora, Spicaria elegans, Penicillium claviforme, Aspergillus niger, Ustilago nuda, U. maydis, Puccinia graminis , and P. striiformis were examined using mass spectrometric techniques. Each species contained at least 3–5 detectable sterol components in the 4‐desmethyl sterol fraction, and, when present, ergosterol was generally the most abundant sterol produced by an individual species. Smaller relative concentrations of fungisterol (ergost‐Δ 7 ‐enol) di‐ and tetraunsaturated C 28 sterols also were found. In some species, fungisterol was the most abundant sterol. In uredospores of rust fungi, stigmast‐Δ 7 ‐enol (C 29 ) was predominant and was accompanied by lower relative concentrations of a diunsaturated C 29 sterol and fungisterol. Cholesterol was found only in the teliospores of the corn smut fungus ( U. maydis ). Application of glass capillary columns to the separation of yeast sterols by gas liquid chromatography is illustrated.
