for the stems of 12 days etioletad plants. It is evident, there- 

 fore, that the formation of insoluble and coagulable proteids 

 is more active in sunlight than in darkness, causing the decrease 

 of albinoses, peptones and diamino-compounds. 



3) The phenomenon of parallelism in the fluctuation of 

 values for peptones and diamino-compounds in the cotyledon at 

 every stage of germination and growthis striking, while of equal 

 interest is the relation shown between the amounts of peptones 

 and albuminoses in the stem ; peptones from the standpoint of 

 molecular complexity, probably having a position between 

 albuminoses and diamino-bodies.

Kusano, S., Exobasidium-Disease of Symplocos japonica. 



(Bot. Mag. Vol. XXI, No. 244, May, 1907. p. (138)-(139)). 



(Japanese). 



Symplocos japonica was found to be attacked by a new 

 Exobasidium related to Exobasidium Symploci which infects 

 Symplocos tinctoria The both fungi infect the young buds, 

 but not in quite the same manner. 



The new fungus was ^named as Exobasidium Symploci 

 japonicse Kusano et Tokubuchi. The diseased part of the 

 host appears whitish in color being covered with a layer of 

 basidium-cells. The basidia are of long club-shape and 120-140 

 H long, with usually 4 and rarely 2 or 5 basidiospores. The 

 spores are curved club- haped and 17-22,7 x 6-7/^ in size, being 

 somewhat larger than those of Exobasidium Symploci which 

 measure after Saccardo 15-12 x 2 H-

This is the first report of the occurrence of Polyporus volv- 

 atus Peck in Japan. The fungus was found parasitic on Pinus

The detailed description is given with three figures.
