Cyclopyxis eurystoma var. gauthieriana Bonnet et Thomas, 1960
Diagnosis: Test with the general shape of the type, with a larger size. The profile is three-quarters of a circle. Large pseudostome (more than half the diameter of the test), with very low invagination, not exceeding 1/5 or 1/6 of the height of the test. Test covering comparable to the type; often coarser elements at the top of the dome.
Dimensions: Test diameter 80-83 µm; in Africa, up to 92 µm; height 60-62 µm; oral invagination 8-10 µm.
Ecology: Wet soil under Juniperus commuted L., near the Batère Tower (Pyrénées-Orientales); Algeria (unpublished documents L. Gauthier-Lièvre and R. Thomas).
Remarks: Although of comparable dimensions, Cyclopyxis kahli Deflandre differs from this variety by a much narrower pseudostome and an ever-increasing invagination.
