PENNSYLVANIAN SPORES OF ILLINOIS 



13. Triquitrites spinosus Kosanke, 1943 



14. T. sp. 



15. Calamospora breviradiata sp. nov. 



16. Lycospora granulata sp. nov. 



17. L. parva sp. nov. 



18. L. punctata sp. nov. 



19. Raistrickia aculeata sp. nov. 



20. R. crinita sp. nov. 



21. Wilsonia vesicatus sp. nov. 



22. "Spherites" sp. 



23. Gen. Nov. (see 5-A coal bed) 



Laevigato-sporites is numerically the 

 most important genus since 54 to 57 percent 

 of the total spore content is ascribed to the 

 genus. L. minutus (Ibrahim) S. W. and 

 B., 1944, and L. pseudothiessenii sp. nov. 

 represent 31 and 21 percent respectively 

 whereas the remaining species of the genus 

 are rather rare. Species of Lycospora repre- 

 sent 32 percent of the spore population with 

 L. granulata sp. nov., L. parva sp. nov., and 

 L. punctata sp. nov. representing 16, 13, 

 and 3 percent respectively. The remainder 

 of the genera and species are of minor nu- 

 merical importance. 



Although this coal bed is not definitely 

 identified outside the Franklin County area 

 it may be equivalent to the Scottville coal 

 bed of Payne (1942). The reason for 

 suspecting equivalence of these two beds 

 is that the lowest range of Wilsonia vesica- 

 tus sp. nov. and the highest range of gen. 

 nov. (see 5-A coal bed species list) is 

 known in both of these beds. 



The following genera and species have 

 been identified from the 3rd Cutler-rider 

 coal bed, macerations 693-C and 545-A, 

 from Franklin County: 



1. Punctati-sporites fene stratus sp. nov. 



2. P. obliquus sp. nov. 



3. P. orbicularis sp. nov. 



4. P. latigranifer (Loose) S. W. and B., 1944 



5. Laevigato-sporites latus sp. nov. 



6. L. ovalis sp. nov. 



7. L. punctatus sp. nov. 



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



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

 and B., 1944 



10. Endosporites formosus sp. nov. 



11. E. plicatus sp. nov. 



12. E. vesicatus sp. nov. 



13. Triquitrites pulvinatus sp. nov. 



14. Calamospora breviradiata sp. nov. 



15. C. sp. 



16. Florinites sp. 



17. Wilsonia vesicatus sp. nov. 



Endosporites is the dominant genus for 

 the first time in the Pennsylvanian of Illi- 

 nois with 45 percent of the spore content 



belonging to the genus. E. formosus sp. 

 nov. and E. plicatus sp. nov. and E. vesica- 

 tus sp. nov. represent 41 and three and one 

 percent respectively of the spore population. 

 Laevigato-sporites contains 25 percent of 

 the spore population with L. minutus (Ibra- 

 him) S. W. and B., 1944, L. ovalis. sp. nov., 

 L. punctatus sp. nov. representing 10, seven 

 and five percent respectively, while L. latus 

 sp. nov. and L. desmoinensis (Wilson and 

 Coe) S. W. and B., 1944, are rare. Punc- 

 tati-sporites orbicularis sp. nov. represents 

 13 percent of the spore population and the 

 remaining species of the genus represent 

 five percent. Species of Calamospora repre- 

 sent seven percent of the spore population. 

 The absence of Laevigato-sporites pseu- 

 dothiessenii sp. nov. from this coal bed in- 

 dicates that the 2nd Cutler-rider coal bed 

 is the upper limit of the species. Lycospora 

 is likewise missing, indicating that the 3rd 

 Cutler-rider coal bed lies above the Scott- 

 ville and below the No. 8 coal beds. 



Scottville Coal Bed 4 



The coal bed called the Scottville coal 

 bed by Payne (1942) lies 35 feet 6 inches 

 below the Scottville limestone in the SW. 14 

 NW. i/i NW. ]4 sec. 16, T. 12 N., R. 9 

 W., Macoupin County. 



The coal bed is characterized by an 

 abundance of Lycospora with L. granulata 

 sp. nov. and L. parva sp. nov., and L. punc- 

 tata sp. nov. comprising 20, 20, and 10 per- 

 cent of the total spore population respective- 

 ly. The genus Laevigato-sporites contains 

 36 to 43 percent of the total spore popula- 

 tion and L. pseudothiessenii sp. nov. repre- 

 sents 23 to 25 percent of this total. L. 

 medius sp. nov. contains five to six percent 

 of the total spore population and L. minutus 

 (Ibrahim) S. W. and B., 1944, eight to 10 

 percent while L. desmoinensis (Wilson and 

 Coe) S-. W. and B., 1944, and L. latus sp. 

 nov. are minor elements insofar as abun- 

 dance is concerned. This is the highest 

 stratigraphic position in which L. pseu- 

 dothiessenii sp. nov. is an important com- 

 ponent of the spore population. It is note- 



4 In an earlier publication (1947) the author used the 

 name First coal bed below the Scottville as suggested 

 bv Ball in a manuscript on the Geology_ of the Carlin- 

 ville quadrangle. Payne's original name is used in this 

 report.
