they differ also in the measurement of their spores. The spores of P. singularis are 

 35 54 x 16 23/4 in size (rarely 58.5/A in length), typical ones being about 42 x 23/*; 

 while those of P. Anemonae-Raddeanae 30 44 x 16 22/i (rarely 50 /A), typical 

 ones about 36 x 19 /x. At first, I was iuclined to include these two forms in one 

 species, but finding the above mentioned differences to be constant, I have here 

 described it as a new species. 



Puccinia melasmioides Tranzsch. 



Sydow, Monogr. Ured., 1, 1904, (538). 

 Saccardo, Syll. Fung., 17, 1905, (357). 



Hab. On leaves of Aquilegia akitensis Huth. 



Honshu. Prov. Shinano: Mt. Shirouma (m. Aug. 10, 1906. M. MIUEA). 



Distrib. Turkestan and Japan. 



REMARKS. The species of Puccinia already known as parasitic on Aquilegia 

 spems to be but a single species with its variety, P. melasmioides and var. 

 Aquilegiae-viridiflorae Karst. The occurrence of Puccinia on the Japanese species 

 of Aquilegia has remained unknown up to this time. Fortunately, I have found a 

 sorus of Puccinia on the under surface of the leaf of Aquilegia aldtensis Huth. 



The teleutosorus is medium in size, elliptical, covered by epidermis, divided 

 into many small compartments by a thick bed of brown paraphyses, more or less 

 pulvinate and black in colour. Teleutospores are oblong-clavate or clavate in shape, 

 truncate or apiculate and thickened (2 6 /ju) at the apex, not or slightly constricted 

 at the septum, attenuated at the base and smooth. They are chestnut-brown at the 

 apex, light brown at the lower cell. Measurements range from 32 to 70 /* in length, 

 from 11 to 17 /A in breadth. Pedicels are short or rarely 10 /* long, persistent 

 and hyaline or light brownish in colour. 



Material of this fungus is very scanty, as I have found only one sorus. 

 Therefore, my description and observation may be incomplete. But in many 

 characteristic points our plant coincides very well to the Turkestan specimen.
