ENUMERATION AND DESCRIPTION OF THE SPECIES OF 



FOSSIL PLANTS KNOWN FROM THE GREEN 



RIVER GROUP. 



CRYPTOGAMS. 



FUNGI. 

 Spliaeria luyricae, Lesqx. 



"U. S. Geol. Eep.," vii, p. 34, pi. ii, fig. 4. 



CHARACEJE. 



CHARA, Waill. 



Cbara? glomerata, sp. nov. 



Plate XXI, Fig. 12. 



Leaves short, in compact, dense, distant or terminal capitules; stem narrow. 



These fragments are not positively referable to Chara on account of 

 the compactness and shortness of the leaves. The branches bearing the 

 capitules are smooth, flexuous, the leaves ? apparently subcylindrical, 

 acute. They may represent flower-bearing pedicels of Platanus like P. 

 racemosa, Nutt. They, however, can scarcely be considered as such, for 

 not the least fragment of Platanus leaves has been found as yet in the 

 Green River Group. 



Hab.— Florissant. U. S. Geol. Expl. Dr. F. V. Hayden. 



MUSCI. 



FONTINALIS, Linn. 

 Fontiiialis pristiua, ep. nov. 

 Plate XXI, Fig. 9. 

 Leaves obscurely two-ranked, crowded, linear-lanceolate, acuminate, ecostate. 

 The leaves are close, gradually enlarged toward the embracing base, 

 about one centimeter long, very narrow. 



Hab. — Florissant, Colorado. The locality indicated as Castello's 

 ranch is the same.
