Abstract
The present paper deals with the results of investigations of seventeen fungi collected in Oze District (Nikko National Park) in July of 1948.
So far as the writer knows, Cercospora Nicolai Bubak is a new addition to the mycological flora of Japan.
By comparing the characters of Leptosphaeria sp. parasitic to Rhododendron metternichii var. Degronianum with the original description of Leptosphaeria Rhododendri. he found that asci and ascospores of the original fungus are quite larger than those of the writer's fungus, so its taxononical study will remain in future.
Allium Iatissimum PROK., Trillium Tschonoskii MAXIM., Epimedium snlphrellum NAKAI and E. coelestre NAKAI are additional new hosts for Alternaria Allii NOLLA, Phyllosticta trillicola TOGASHI and Aecidium Epdmedii P. HENN. et SHIRAI respectively.
