 claytoniata.

 Puccinia gigantispora Bubak, Sitz.-ber. Bohm. Ges. Wiss. 1901:

Aecia hypophyllous, occasionally caulicolous, on yellowish or 

 reddish spots, roundish or elongated on veins; aeciospores 16-23 

 by 19-26 At; wall about 1.5 m thick. 



Telia amphigenous, gregarious, arising about the secondary 

 aecia or later scattered, small, long covered by the epidermis; 

 teliospores cylindrical or linear, obtuse or truncate above, nar- 

 rowed below, lower cell often twice the length of the upper, 13-19 

 by 45-87 At; wall 1-1.5 m thick, smooth^or with one to three longi- 

 tudinal ridges, apex 3-12 /x thick, usually darker; pedicel con-

On Ranunculaceae: 



Anemone cylindrica A. Gray, A. globosa Nutt., and A. nar- 



cissiflora L.

Note. — This species is separated from Puccinia deBaryana 

 Thuem. by its lack of stroma surrounding the telia. Dasyspora 

 Anemones-virginianae (Schw.) Arth. is frequently found on the 

 same host with these two species and also with heteroecious aecia 

 belonging to Dicaeoma Clematidis (DC.) Arth. 



10. Allodus opposita sp. nov. 



Aecia seen of secondary form only, hypophyllous, gregarious 

 on discolored spots; small, cupulate; aeciospores subgloboid, 

 14-18 by 18-24 fx; wall 1-1.5 m thick, finely verrucose.
