Type description

van Geel et al (1983b): Spores trilete, reticulate, circular to subtriangular in outline, 67.9-92.2 µm in diameter, the narrow leasura arms running to the edge of the proximal face, leasura forming part of the reticulum. Muri 4-5 µm high, the outer parts becoming hyaline, rendering the spores somewhat vague in outline. Meshes of the reticulum 5-12 µm in diameter at the proximal, and 11-15 µm at the distal side. The fossil spores were identified by J. Landwehr (Le Montat, France) as R. cf. sorocarpa.
