studies in Chinese Fungi, 



{With Plate I.) 



By 



Ichiro Miyake, Nogakuslii. 



The following descriptions are based on the materials col- 

 lected by myself in South China in 1908, and in Peking and its 

 vicinity in 1910 and 1911. Most of them are already known 

 from other parts of the world, but some of them are new, as 

 far as I can aware. Besides there are a few species which are 

 unable to be exactU^ determined at present. As our knowledge 

 of the fungal flora of China is very meagle, I intend to make 

 further collections and continue the study.
