 Whilst it is generally accepted that "Tortilicaulis" was moss-like, it has not yet been recovered in a sufficiently good state of preservation to allow the detailed study necessary to firmly assign it to a taxonomic group.Fossils consist of an elongate apical sporangium (spore-forming organ), which may be branched, with spiralled walls attached to an undivided stalk that is also twisted.Unusually for plants of its time, spores of "Tortilicaulis" were covered all over with small granules.
