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



The most abundant species is Lycospora 

 punctata sp. nov. which comprised 25-28 

 percent of the total spore content. The 

 genus Lycospora is the most abundantly 

 represented genus making up 35 to 36 per- 

 cent of the total spore content. Punctati- 

 sporites is next in numerical importance 

 with 20 to 21 percent of the total spore 

 population. P. latigranifer is the most 

 abundant species; it averages about 19 per- 

 cent of the total spore population. Cala- 

 mospora represents 16 to 18 percent of the 

 spore population and C. mutabilis (Loose) 

 S. W. and B., 1944, is most important with 

 13 to 14 percent. Laevigato-sporites rep- 

 resents 14 to 15 percent and L. minutus 

 (Ibrahim) S. W. and B., 1944, is the most 

 abundant species with 9 to 10 percent of 

 the spore population. L. pseudothiessenii 

 sp. nov. is exceedingly rare, in contrast with 

 its abundance in No. 6 and the Cutler 

 coal. Punctati-sporites orbicularis sp. nov. 

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

 1944, are not known to occur below this 

 bed. 



Cutler Coal Bed 



The name Cutler was applied by Bell, 

 Ball, and McCabe (1931) to a coal bed 

 exposed in the vicinity of Cutler, Perry 

 County, Illinois. Stratigraphically the 

 Cutler coal bed occupies part of the succes- 



sion between the Cutler limestone above and 

 the Galum limestone below in the vicinity 

 of Cutler. In some places in southern Illi- 

 nois, as in Franklin County, the Bankston 

 coal bed lies a few feet below the Cutler 

 bed. A sample of the Cutler coal bed 

 from the SW. \/ A SW. \/ A sec. 34, T. 5 S., 

 R. 4 W., Perry County, Illinois, has been 

 macerated and the spores identified. A 

 coal bed commonly encountered in diamond 

 drilling in Franklin County lies at the 

 position of the Cutler coal bed of Perry 

 County. Three such cores of this bed from 

 Franklin County have been examined for 

 spores: maceration 536-D, 458 feet 2 inches 

 to 460 feet 9i/ 2 inches, SE. \/ A NW. ]/ A sec. 

 16, T. 6 S., R. 1 E.; maceration 537-E, 

 518 feet 8 inches to 520 feet 9i^ inches, 

 SE. 14 NW. 14 SE. 14 sec. 27, T. 6 S., 

 R. 2 E. ; and maceration 553-D, 426 to 427 

 feet, SW. 1/4 NW. 14 sec. 6, T. 7 S., R. 

 3E. 



The Cutler coal bed is commonly the 

 thickest McLeansboro coal bed in Franklin 

 County, but the bed is variable in thickness, 

 ranging from less than 1 to slightly less than 

 3 feet. The coal bed is composed of normal 

 bright banded coal and is not benched by 

 shale or clay partings. However, lenses of 

 pyrite have been observed. 



The following genera and species have 

 been observed in Perry and Franklin coun- 

 ties unless otherwise noted:
