CRYPTOa^lVEI^. 



FUNGI. 



Order PYRENOMYCETES. 



Sph^kia pkoblematica, sp. nov.' 



PI. XXXI, Fig. 2, 2a. 



• One of the specimens of Sfercidin Snowii, PI. XXXI, Fig. 2, is partly 

 covered by very distinct round or oval, even sometimes triang-ular dots, 0.5 

 to 1""™ in diameter. Each dot has two prominent marginal ring-s surround- 

 ing a small central areole (Fig. 2a, enlarged). It represents a species of 

 Spha?ria and greatly resembles S. Braunii Heer.^ 



SOLBROTIUM? SPECIES. 

 PI. LIX, Figs. 4, 4a. 



The leaf o( Macclintockia cretacea Heer, figvired on PI. LIX, Fig. 4, shows 

 a parasite, which is of a doubtful nature and is so obscure that it has not 

 been specifically named. The fragment from Kansas has a line of parasites 

 which are oval, acute at the lower part, concave, with a convex point in the 

 middle; they are placed along the lateral nerves in a row of ten or more and 

 by their position only are comparable to Sderotium cinnamomi Heer, FI.

'This species was described bnt not specifically named by Prof. Lesquereiix under his description 

 of Sterculia Snowii (q. v.), where he also says of it: "Though the specie.*) can not be identified the 

 generic reference is evident." In order that it may be independently referred to I have ventured to 

 call it SpJueria problematica. — F. H. K.
