In addition to the species listed above, 

 forms belonging to Calamospora and Punc- 

 tati-sporites have been observed but are not 

 described because of the lack of adequate 

 good specimens to warrant description. 



Reynoldsburg Coal Bed 



Spores are numerically abundant in the 

 Reynoldsburg coal bed, and 11 genera in- 

 cluding 15 species are recognized. The 

 Reynoldsburg coal bed at the single locality 

 sampled is characterized by a dominance of 

 Denso-sporites reynoldsburgensis sp. nov. 

 which comprises 65 percent of the total 

 spore content. Further, D. indignabundus 

 (?) (Loose) S. W. and B., 1944, and 

 Lycospora pellucidus ( Wicher) S. W. and 

 B., 1944, appear to be restricted to this 

 bed. Lycospora, the dominant genus of the 

 Battery Rock and Wayside coal beds, is 

 subdominant, representing only 20 percent 

 of the total spore content. Nevertheless it 

 is an important genus for correlating the 

 Reynoldsburg coal bed because four species 

 of the genus are known to be present, or 

 two more than are found in either the 

 Battery Rock or the Wayside coal beds. 

 The presence of species of the genus Laevi- 

 gato-sporites is of utmost importance be- 

 cause it is the first occurrence of the genus 

 in Pennsylvanian time in Illinois, and be- 

 cause spores of this type are known to the 

 present day. The following important 

 genera have not been observed in the 

 Reynoldsburg: Alati-sporites, Cirratrira- 

 dites, Reinschospora, and Schulzospora. 

 The following genera and species have been 

 identified from the Reynoldsburg coal bed, 

 maceration 618, SW. \/ A sec. 32, T. 11 S., 

 R. 4 W., Johnson County, Illinois: 



1. Granulati-sporites pallidus sp. nov. 



2. G. granulatus Ibrahim, 1933 



3. G. gibbosus (Ibrahim) S. W. and B., 1944 



4. Reticulati-sporites splendens sp. nov. 



5. Laevigato-sporites ovalis sp. nov. 



6. L. desmoinensis (Wilson and Coe) S. W. 

 and B., 1944 



7. Denso-sporites reynoldsburgensis sp. nov. 



8. D. indignabundus (?) (Loose) S. W. and 

 B., 1944 



9. Triquitrites priscus sp. nov. 



10. L. pseudoannulata sp. nov. 



11. L. granulata sp. nov. 



12. L. micro papillatus (Wilson and Coe) S. 

 W. and B., 1944 



13. L. pellucidus (Wicher) S. W. and B., 1944 



14. Florinites diver siformis sp. nov. 



15. Florinites antiquus Schopf, 1944 



The addition to the species listed above, 

 five species of the following genera have 

 been observed in very limited numbers and 

 are not described: Endosporites, Calamo- 

 spora, Punctati-sporites , and Wilsonia gen. 

 nov. 



Conclusions 



The spores of three Caseyville coal beds 

 have been examined. Spores from 13 genera 

 have been identified, and of these, seven 

 species and one genus are restricted to the 

 Caseyville coal beds. Laevigato-sporites and 

 Florinites appear for the first time in the 

 Pennsylvanian of Illinois in the Reynolds- 

 burg coal bed. Alati-sporites, Cirratrtra- 

 dites, and Reinschospora (which are present 

 in the Tradewater group) have not been 

 found in Caseyville coal beds. 



The Wayside, Battery Rock, and Rey- 

 noldsburg coal beds, of Caseyville age, have 

 a distinctive spore population which should 

 enable the identification of coal beds at 

 these horizons outside of Illinois. Attempts 

 at correlation of the Caseyville coal beds 

 and "lower Pennsylvanian" beds of western 

 Illinois have led to the conclusion that the 

 "Sub-Babylon" 1 coal bed exposed near 

 Tarter Bridge in Fulton County, sec. 2, T. 

 5 N., R. 1 E., and the Babylon coal bed 

 are younger and therefore may be of early 

 Tradewater age. Correlation of Illinois 

 Caseyville coal beds with those of western 

 Kentucky has not been attempted. 



TRADEWATER GROUP 



The Tradewater group, formerly called 

 upper Pottsville, is known from outcrops 

 in southern, western, and northern Illinois. 

 Recent publications place the top of the 

 Tradewater group at the bottom of the 



1 A 2 to 3 inch coal bed called the "Sub-Babylon" 

 coal bed by Schopf in maceration notes. It lies above 

 the Mississippian strata and below the Babylon coal bed.
