Re-examination of species ascribed to the genus Labyrinthomyces plus our collections of related undescribed taxa revealed three distinct morphological groups which we segregate at the generic level. All have globose to ellipsoid spores ornamented with amorphous, hyaline warts or ridges. Labyrinthomyces is retained as a monotypic genus characterised by a brown-tomentose peridium and paraphyses half as long as the asci. Dingleya contains six species (two newly described here) with tessellate-cracked to verrucose peridia. Reddellomyces has four species (one newly described) with white to pale brown, smooth peridia. The last two genera are known only from Australasia.
