In the early summer of 1922, the writer visited Lake Akan with Messrs. 

 H. Suzuki and A. Abe, and collected many parasitic fungi on Mt. Meakan 

 near the lake. The second visit was undertaken for the purpose of botanical 

 collection with Mr. M. Okamoto in the summer of 1923 and we spent a week 

 at the lakeside. In the autumn of 1925 the writer made a third visit with 

 Mr. M. Tatewaki, and especially endeavoured to get material for study on the 

 mycological flora of the vicinity of Lake Akan. The fourth visit was made by 

 the writer with Mr. M. Tatewaki in the latter part of August 1926 for the 

 same purpose. 



During these four excursions, more than 200 species of fungi including 98 

 species of Uredinales have been collected. Among them, the following two 

 rust fungi are considered as new to tlie mycological flora of Japan : Pucclnia 

 nralensis Tranzsch. and Thekopsora guttata (Schrot.) Syd. The present short 

 paper is intended to report the Uredinales collected in the vicinity of Lake Akan.
