RADSTOCK SERIES OF THE SOMERSET AND BRISTOL COAL FIELD. 339 



SYNOPSIS OF SPECIES. 



Fungi. 



Excipulites, Goppert, 1836, Diefossilen Farrnkrauter, p. 262. 



Excipulites callipteridis, Schimper, sp. 



Excipula callipteridis, Schimper, Traite d. paleont. veget., vol. i. p. 142, and Explanation to 



pi. xxxii. figs. 6, 7. 

 Excipula callipteridis, "Weiss, Foss. Flora d.jiingst. Stk. u. d. Rothl., p. 19. 



Remarks. — On Sphenopteris neuropteroides. The minute fossils included 

 here appear to be similar to those described by Schimper and Weiss as occur- 

 ring on Callipteris conferta, Brongt. The central opening is not very well seen 

 in our examples, which are situated on the limb of the pinnules between the 

 veins. 



It is interesting to find that both Lesquereux (Coal Flora of Pennsyl., 

 vol. i. p. 207, pi. xxxviii. fig. 2 ; P. anceps — Sphen. neiwopteroides) and Zeiller 

 (Bull. soc. geol. de France, 3 e se>., vol. xii. p. 192) have noted the occurrence 

 of these small fossils on the pinnules of Sphen. neuropteroides. 



There seems little reason to doubt that Excipulites comprises a group of 

 minute parasitic fungi. 



Locality : — Radstock.
