Exsiccati : Entyloma Ranunculi forma Thalictri Farl., on Thalictrum 
dioicum , Rab.-VV int., Fungi Eur., 3406, Roum., Fungi Gall., 3961; Enty¬ 
loma Thalictri Schrot., on Thalictrum dioicum , Ell., N. A. Fungi, 1489, 
Seym. & Earle, Econ. Fungi Clinton Ust. Supp., C 34. 
Sori in leaves, forming small angular yellowish or reddish areas, 
about 1-2 mm. or by confluence more extended, often rather indefi¬ 
nite ; spores often not. very abundant, hyaline to yellowish, ovoid 
to subspherical or occasionally somewhat angled and more irregular, 
thin to medium thick walled, smooth, small, about 8-13 p, in length; 
conidia apparently hypophyllous. 
Hosts : Thalictrum dioicum , Wise, (type E. Ranunculi f. Thal¬ 
ictri)] T. polygamum, Conn.; T. purpurascens, Ill. 
European specimens of this species have not been available for 
examination. Some of the specimens approach very closely to 
Entyloma Ranunculi under which species the specimens on T. di¬ 
oicum were first placed as a form. In the Host index of N. A. 
Fungi, Oylindrosporium Ranunculi f. Thalictri Ell. & Ev., and 
Cylindrosporium (Jlematidis Ell. & Ev., are given as synonyms of 
this species, apparently on the supposition that they are the conidial 
stage. Positive evidence of this, however, seems lacking as yet.
