Stigmaria ficoides is a type designation for roots of scale trees (Lycopods). The main roots have scars, usually ovate, where the rootlets once attached. In this specimen you can clearly see not only the main root but rootlets coming off of the main root at right angles on both sides.
The white highlights on this plate are iron oxide left from the original plant material. The site where this was found is part of the same formation as the famous St Clair locality, which is known for its white fern fossils.
