" based on cell morphology - it differs from the type by the presence of nodular wall thickenings. Usually, thickenings are located on the inner corners and opposed points of adjacent lobes. Sometimes adjacent lobes are connected by ridge-like thickenings. It was noted that this variety is not a teratological form, because similar wall thickenings were found in numerous cells collected in several sites. Also, no transitional forms were seen between the nodular and the typical forms and the two forms occurred side by side in some samples. Dimensions: 70-74 x 80

were found in lake environments. In the Philippines the water bodies were characterized by clear water, covered by plants, containing detritus and other remains of higher plants. In Indonesia it was recorded from a crater lake (Suppl. material 2). No data on physico-chemical environmental variables was present for these water bodies.
