The chlamydospores of Ustilago maydis, U. nuda, and Sphacelotheca reiliana were analyzed by gas chromatography and mass spectrometry for their hydrocarbon contents. For the first time we observed that they contain paraffinic hydrocarbons; the average contents were 42, 58, and 146 parts per million, respectively. n-Alkanes having odd numbers of carbon atoms predom-inate, with carbon-chain lengths ranging from C14 to C37. The major alkanes are n-C27 in U. maydis, n-C27 and n-C35 in U. nuda, and n-C29 in S. reiliana. Each type of spore carried a distinctly characteristic population of hydrocarbons.
