Galeripora halaurula  Useros et al., 2023

Diagnosis: Shell composed of small building units, but there is frequently a smooth organic matrix that covers them and prevents their observation, particularly in the oral side. On the aboral side the building units give it a rough toad-like texture. There is no cement between them. The center of the oral side is concave, but with a smooth transition, without a clearly delimited preapertural area. The aperture is small in relation with the diameter of the test; it has a lip and is surrounded by several relatively large pores. In some individuals there were a few other isolated pores on the margins of the oral side. In the lateral view it looks like a trapezoid, but the border protrudes. It resembles a hat. On the aboral side there are some smooth, radial ridges. In most dead individuals the test was flattened.

Dimensions: According to Useros et al. (2023): Shell diameter 65—98 μm; aperture diameter 11—20 μm;  aperture diameter with rim 12—22 μm; height 28.11 μm (n=1).

Habitat: Terrestrial, growing on aerophilic mosses in dry soil, with salt deposits. Environmental metabarcodes showed its presence in mosses growing on sandy beaches, exposed to the sea breeze. It has also been found, however, away from the sea or any salt source; this suggests that this species is also euryhaline.

Geographical distribution: Salobral de Ocaña, Toledo, Spain (39º59′N,3º37′W).

Remarks: Galeripora halaurula is morphologically very similar to Galeripora arenaria, G. sitiens, G. bufonipellita and G. balari.
