Nebela tincta f. galeatea; Killarney NP, Ireland, 2025
Nebela tincta f. galeata Jung, 1936
Diagnosis: The test is broadly pyriform, laterally compressed, and bears a lateral keel approximately 5 µm wide. A small lateral pore is present on each side. The test is composed of small oval particles, likely obtained from prey (i.e., euglyphid testate amoebae). The aperture is oval and linear.
Dimensions: According to Jung (1936): Shell length: 140—150 µm.
My measurements: 130—146 µm long.
Ecology: Dry mosses, Sphagnum.
Remarks: This form resembles Nebela aliciae, which is smaller. It is quite possible that shells in other populations exhibit larger or smaller dimensions.
