Taxonomic remark Substitute name for Variolaria Sternberg 1820, non Persoon 1794. (Index Nominum Genericorum). A form genus for roots which may belong to genera assigned to Lepidodendraceae, Sigillariaceae, or Lepidocarpaceae. From Cleal & Thomas, 2018: Stigmaria is now used for the rhizomorphs of various arborescent lycopsids with upright stems assignable to fossil-genera such as Lepidodendron Sternberg, Lepidophloios Sternberg, 1825 and Sigillaria Brongniart. The Stigmaria rhizomorphs that were attached to these different types of upright stems are indistinguishable morphologically and anatomically, and so it is impossible to assign them to a particular type of stem. Stigmaria should, therefore, be retained for these fossil rhizomorphs in all modes of preservation (see Thomas and Seyfullah 2015). [details]
