Catalog entries: Lithocarpium monikae

Original description: Outer gown with meshes 5-10µm in diameter. The diameter of entire skeleton about 150-250µm. The central mass (or spiral?) looks very similar to that in L. fragilis although L. monikae differs from L. fragilis. The latter have no pronounced radial spines (or rods), and the space between the central mass and the outer gown in L. fragilis is filled with irregular meshes (Plate 4, Figures 3, 4). In L. monikae the construction is similar to that in Rhizosphaeridae: there are radial spines connecting central mass and external layer.
Remarks on original description: Description is based on 26 specimens.
