 The fossils of "Parka decipiens" seem small circular, elliptic or irregular patches reaching a diameter of , with a reticulate structure showing small coaly discs.These discs contain a mass of what could be spores.Ultrastructural examination of these spores has shown that they lack the y-shaped trilete mark, a Y-like scar, that is characteristic of Silurian and Devonian pteridophytes.
