SPECIES, AUTHORITY S. cylindricus (Horst) Dybová & Jachowicz 1957, p. 56, pl. 1, fig. 1-4; "nom. nov. Kalgutkar & Jansonius 2000" [sic].
LOCATION Upper Silesian Basin, Poland.
ORIG DESCRIPTION* "EMENDED" DESCRIPTION (Dybová & Jachowicz 1957, p. 56): Spore outline is oval (resembling a small tube). The surface of the exine is smooth. Across the middle of the spore there is a characteristic thickening of the exine - [a] torus. A dehiscence mark -- either dilete or trilete -- has not been observed. The color is light brown; the torus is dark brown. The average size of the spore 25 x 40 ¬µm. State of preservation is good.

K&J REMARKS Elsik (1990b) created the genus Felixites to include two-celled spores from Carboniferous strata that were included first in the genus Sporonites (R. Pot.) Ibr. 1933 (as Sporonites pollenisimilis Horst, 1943, 1955), and later in Chaetosphaerites Felix 1894 by Butterworth & Williams (1958). Elsik included two species in Felixites, F. pollenisimilis (Horst 1943) Elsik 1990b and F. playfordii Elsik 1990b.

Because Dybová & Jachowicz included the holotype of S. pollenisimilis (Horst, 1955, pl. 24, fig. 84) in the synonymy of S. cylindricus -- which, without further explanation, they published as both a new name and a new combination, not as a new species -- the latter name is illegitimate, and an obligate junior nomenclatural synonym of S. pollenisimilis.
