Parasitic Fungi of Illinois. 195 



long or elliptical, abruptly and rather deeply constricted, apex 

 thickened and mostly narrowed to a rounded point, lower seg- 

 ment usually longer and narrowed to the pedicel, surface 

 smooth, 12-21 by 30-50 ^; pedicel hyaline, usually less than 

 the length of the spore, but sometimes longer. 



On Aletris farinosa : Millers, Indiana, near the Illinois 

 line, July 4, 5592, II., E. J. Hill. It probably occurs in Illi- 

 nois. 



P. smilacis, Schw. 



IT.. III. Hypogenous. Spots small, numerous, brick-red; 

 sori scattered or irregularly circinate, punctiform or elonga- 

 ted, surrounded by the ruptured epidermis, and by a row of short 

 club-shaped paraphyses. II. Spores oval, slightly echinulate, 

 pale, 21-27 /*, on fragile pedicels. III. Spores broadly ellipti- 

 cal, conspicuously constricted, upper segment considerably 

 rounded or obtusely pointed, often narrowing below to the 

 pedicel, dark colored, smooth, 21 by 36-42 j*; pedicel thick, 

 tinted, as long as the lower segment.

 able, scattered, often very numerous and conspicuous, the rup-
