SPORE DISTRIBUTION — CASEY VILLE 



81 



T. rotatus ? (R) 



C. verrucosus (R) 



Triletes globosus and Cystosporites varius 

 each account for about 45 percent of the 

 total large spore content. T. glabratus is 

 not represented again in the Pennsylvanian 

 of Illinois until its occurrence, much higher 

 stratigraphically, in the Carbondale Group. 

 A coal (maceration 142), identified as 

 "Makanda" (?) or Battery Rock (?) (SE14 

 SE14 sec. 29, T. 10 S., R. 1 W.), Jackson 

 County, contained an assemblage very sim- 

 ilar to that of the previously described 

 maceration 906, but with slight difference 

 in abundance ratios and the additional 

 presence of a few spores of T. subpilosus. 



Reynoldsburg Coal 



Large spores were extremely abundant in 

 the Reynoldsburg Coal (maceration 618) 

 from Johnson County, but only a few gen- 

 era and species were represented. Triletes 

 globosus and Spencerisporites cf. 5. radiatus 

 each represented more than 45 percent of 

 the total large spore content. A few spores 

 of T. globosus var. (B) and Cystosporites 

 giganteus also were present. In addition, 

 the coarse residue contains much cuticle 

 similar to that illustrated by Bartlett 

 (1929). Kosanke (1950) reported that the 

 small spore content of this coal is charac- 

 terized by a dominance of Densosporites 

 reynoldsburgensis. 



This is the uppermost occurrence of 

 abundant spores of both Spencerisporites 

 cf. 5. radiatus and those typical of Triletes 

 globosus. The assemblage is unlike any 

 found in younger, overlying beds of Trade- 

 water age. 



Miscellaneous Samples 



The coarse residue from a coal of Casey- 

 ville age (maceration 910), sampled from a 

 gob pile around the shaft of an abandoned 

 mine in a fault block zone in Pope County, 

 contained spores of the following genera 

 and species: 



Triletes rotatus (A) 



Monoletes (A) 



T. triangulatus (P) 



T. superbus (R) 



This assemblage is unlike that of any other 

 Caseyville age coal examined in that it con- 



tains abundant spores of both T. rotatus 

 and Monoletes. 



The following genera and species were 

 identified from a Cannelton Coal (macera- 

 tion 780) from Perry Countv. Indiana: 

 Triletes superbus (A) 



T.auritus (A) 



T. triangulatus (P) 



Spencerisporites cf. S. radiatus (R) 



Monoletes (R) 



Another sample from Indiana from a coal 



in the Mansfield (?) Sandstone (maceration 



779), Owen County, Indiana, contained 



spores of the following genera and species: 



Triletes rugosus (A) 



T. cf. T. hirsutus (A) 



T. auritus (R) 



Monoletes (R) 



Renisporites? n. gen. (R) 



In Illinois, T. rugosus is not known below 

 the Murphysboro, Rock Island (Xo. 1), and 

 New Burnside Coals of the Tradewater 

 Group; Renisporites is restricted to the 

 Tarter and Willis Coals; T. cf. T. hirsutus 

 is known only from the Tarter, Pope Creek, 

 and Rock Island (No. 1) Coals. 



Two samples (macerations 203 and 755) 

 of coaly streaks in sinkhole deposits from 

 Lehigh Quarry in Kankakee County, Illi- 

 nois, and one sample (maceration 455) from 

 similar deposits in Lincoln Quarry in Will 

 County, Illinois, were examined. All three 

 samples contained aphanozonate spores sim- 

 ilar to those of Triletes fulgens Zerndt. The 

 sample from Will County also contained 

 abundant seed membranes and at least one 

 spore of T. rotatus. 



Outcrop samples from fifteen coals of the 

 Black Creek, Mary Lee, and Pratt Groups 

 in the Warrior Basin, Walker County, Ala- 

 bama, were compared. In general, Triletes 

 mamillarius, T. subpilosus, and spores prob- 

 ably referable to T. globosus var. (B) are 

 fairly common in some of these coals. Al- 

 though resin rodlets, usually associated 

 with the Medulloseae, occur sporadically, 

 medullosan spores (Monoletes) were not 

 seen. T. praetextus is represented abun- 

 dantly in the Pratt Coal. 



On the basis of a study of the small spores 

 of these coals and those from well samples 

 from the Warrior Basin of Mississippi,
