Carbohydrates released during acid hydrolysis of intact cells ofDipodascus were studied by gas-liquid chromatographic analysis as their trimethylsilyl derivatives. In addition, cells were characterized by pyrolysis gas-liquid chromatography and pyrolysis mass spectrometry. The data obtained support the classification ofDipodascus uninucleatus in a separate genusDipodascopsis. Glucuronic acid is present inD. uninucleatus and, therefore, a possible affinity to fungi classified in the Zygomycetes is considered.Dipodascus aggregatus andDipodascus australiensis were found to be rather different, but very close toGeotrichum candidum and related species.
