long as the diameter of pilens, and further in having pilens meagre 

 in flesh and of a bright yellow color. 



Of the numerous species of Pleurotus, so far as I am aware, 

 the following ten have hitherto been reported to be luminous : 



Pleurotus Gardneri Berk. 1 ' 



PI. illuminant Müll, et Berk. 2) ; Queensland, Australia. 



PI. facifer B. et C. 3) ; Pennsylvania. 



PL nidiformis Berk. 4) ; Swan River, Australia. 



PI. Lampas Berk. 5) ; Swan River, Australia. 



PL noctilucens Lev. 6) ; Manila, P. I. 



PL oleareus D. C. 7) ; Europe and America. 



PL Prometheus B. et C. 81 ; Hongkong. 



PL candescens Müll, et Berk. 9) ; Melbourne, Australia. 



PL phosphorus Berk. 10) ; Tasmania, Australia. 



To the above list should now be added Pleurotus japonicus of 

 Japan. 



III. Habitat and Distribution. 



Pleurotus japonicus seems to be widely distributed in Hondo, 

 Shikoku and Kiushiu. It has been found in the Aomori Prefecture 

 at the northern end of Hondo as well as in the Kagoshima Pre- 

 fecture in the southern part of Kiushiu. From other islands of

 that island also. So far as my experience reach, I should say
