Laevigato-sporites j Lycospora, and Cala- 

 mospora are the most abundant genera, and 

 the presence of five species which appear to 

 originate in this bed helps to characterize 

 the Davis and Wiley coal beds. 



Dekoven and Greenbush Coal Beds 



The Dekoven coal bed of western Ken- 

 tucky and southern Illinois was correlated 

 by Wanless (1939) with the Greenbush 

 coal bed of Warren County in western 

 Illinois, a correlation corroborated by fossil 

 plant spores. The Dekoven type locality is 

 in Union County, Kentucky, and the bed 

 was originally called the "3-foot coal" by 

 Owen (1856). In 1857, he called the 3- 

 foot coal the No. 6 coal bed of Kentucky. 

 This coal bed was named the Dekoven coal 

 bed by Lee (1916) for an opening at De- 

 koven. According to Lee (1916), the De- 

 koven coal at the type locality measured 44 

 inches in thickness but it generally did not 



exceed three feet elsewhere. This coal 

 bed locally has been called the "Gas" coal 

 since it has been used in the production of 

 gas. 



The Greenbush coal bed is named from 

 an exposure in a ravine tributary to Swan 

 Creek in the E. \/ 2 sec. 24, T. 8 N., R. 1 

 W., Greenbush Township, Warren Coun- 

 ty, Illinois, and additional exposures are 

 known from Fulton County, Illinois. 



The following genera and species have 

 been identified from the Dekoven coal bed, 

 maceration 519 A-B, Williamson County, 

 and Greenbush coal bed, maceration 592, 

 Fulton County, unless otherwise noted : 



1. Punctati-sporites foveatus sp. nov. 



2. P. fenestratus sp. nov. 



3. P. firmus (Loose) S. W. and B., 1944 



4. P. verrucifer sp. nov.* 



5. Granulati-sporites aculeolatus sp. nov. 



6. Alati-sporites hexalatus sp. nov. 



7. Laevigato-sporites punctatus sp. nov. 



8. L. ovalis sp. nov. 



9. L. robustus sp. nov. 



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

 and B., 1944 



11. L. minutus (Ibrahim) S. W. and B., 1944 



12. L. minimus (Wilson and Coe) S. W. and

18. T. pulvinatus sp. nov. 



19. T. protensus sp. nov. 



20. T. arculatus Wilson and Coe, 1940 



21. Calamospora breviradiata sp. nov. 



22. C. straminea Wilson and Kosanke, 1944

The Dekoven and Greenbush coal beds 

 are readily differentiated from the coal beds 

 below and above. Laevigato-sporites , Tri- 

 quitrites, and Lycospora are the most abun- 

 dant genera represented. Triquitrites 

 reaches its maximum abundance, and Lae- 

 vigato-sporites pseudothiessenii sp. nov. 

 apparently originated at this time and is a 

 dominant member of the flora throughout 

 the Carbondale and early McLeansboro 

 time. 



Conclusion 

 Spores occur abundantly in the coal beds 



'' Observed only in Wiley coal bed. 

 h * Observed only in Davis coal bed. 



Two specimens found only in the Dekoven coal bed.
