PENNSYLFANIAN SPORES OF ILLINOIS 



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

 1944, are most comon and six other species 

 of the genus are present. The genus 

 Lycospora is next in numerical importance 

 and its abundance varies from 20 to 30 per- 

 cent. It may be somewhat more abundant 

 in southern Illinois. Calamospora, Cirratri- 

 radites, and Punctati-sporites follow succes- 

 sively in line of numerical importance. 



It is sometimes difficult to identify the 

 No. 6 and 5 coal beds in portions of 

 southern Illinois where only rotary logs 

 are available for study. However when 

 samples of coal from these rotary holes are 

 available, it is possible to identify the beds. 

 In the Engle- Waddle No. 1 well in Wa- 

 bash County (fig. 6) the interval between 

 No. 6 and No. 5 coal beds attains the 

 somewhat unusual thickness of 125 feet; 

 hence the base of the black shale represent- 

 ing the position of the No. 5-A bed about 

 65 feet below No. 6 bed would probably 

 have been identified as the position of the 

 No. 5 coal bed had not the identity of the 

 No. 5 at 125 feet below the No. 6 been 

 determined by means of fossil spores. 



No. 5-A Coal Bed 



Cady (1916, p. 45) recorded the presence 

 of a coal bed in Williamson and Saline 

 counties which stratigraphically was be- 

 tween the No. 5 and No. 6 coal beds. In 

 1919, Cady numbered this coal the 5-A 

 bed and correlated it with the Briar Hill 

 (Kentucky No. 10) coal bed. This coal 

 bed is thin, and in some places divided by 

 one or two shale partings. 



The 5-A coal bed is readily differentiated 

 from either the No. 5 or 6 coal beds, and 

 most certainly differs from the Grape Creek 

 coal bed of Vermilion County with which 

 it has been correlated by Wanless (1939). 



The following genera and species have 

 been identified from the 5-A coal bed from 

 Gallatin (maceration 633 A-B) and Frank- 

 lin counties (maceration 507 A-B) : 



1. Punctati-sporites fenestratus sp. nov. 



2. P. obliquus sp. nov. 



3. P. verrucifer sp. nov. 



4. P. quaesitus sp. nov. 



5. P. sp. 



6. Granulati-sporites granularis sp. nov. 



7. Laevig ato- sporite s ovalis sp. nov. 



8. L. pseudothies serin sp. nov. 



9. L. punctatns sp. nov. 



10. L. robustus sp. nov. 



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

 and B., 1944 



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



13. Triquitrites pulvinatus sp. nov. 



14. Calamospora breviradiata sp. nov. 



15. C. hartungiana Schopf, 1944 



16. C. sp. 



17. Lycospora punctata sp. nov. 



18. L. granulata sp. nov. 



19. Raistrickia protensa sp. nov. 



20. R. crinita sp. nov. 



21. R. sp. 



22. Florinites sp. Schopf, 1944 



23. Schopfites sp. 



24. Gen. Nov.* 



Granulati-sporites granularis, Raistrickia 

 protensa sp. nov., and the new form listed 

 as a new genus on the genera and species 

 list all are unknown from the coal beds 

 below 5-A. Schopfites is not known to occur 

 above this horizon. 



No. 6 Coal Bed 



The Herrin (No. 6) coal bed from 

 Franklin and Fulton Counties in southern 

 and western Illinois and the Grape Creek 

 coal bed from Vermilion County in eastern 

 Illinois are correlated as the same bed on 

 the basis of their content of small spores. 

 Samples from these three respective counties 

 have been investigated as well as collections 

 from various other counties. 



The following genera and species have 

 been identified from the No. 6 coal bed 

 from each of the three counties mentioned 

 above except as noted : 



Punctati-sporites fenestratus sp. nov. 



P. obliquus sp. nov. 



P. triangularis sp. nov. 



P. quaesitus sp. nov.

* A new genus of bladdered grains abundant in Iowa, 

 yvhich^ is _ being described by L. R. Wilson, is also present 

 in Illinois. 



** Has not been observed below the blue band.
