New information was obtained on the phylogeny of Zygomycetes. PCR-RFLP analysis showed ITS1/2 rDNA to provide appropriate markers for genetic studies on Zygomycetes at the population and species levels. The use of several restriction enzymes allowed discrimination between genera and species of Mortierellales and Mucorales. ITS1/2 sequence analysis clearly indicated a deep, ancient and distinct dichotomy of Mortierellales and Mucorales. The data do not fully support the current concept of Mucorales, which recently included the family Umbelopsidaceae, but support the distinctiveness of the Umbelopsis group, which includes Mortierella turficola. The data support the hypothesis of polyphyly of Absidia and are consistent with the hypothesis of polyphyly of Mucor. (c) 2006 The British Mycological Society. Published by Elsevier Ltd.
