1. The bacidio-spores kept in distilled water or in a decoction of 

 oak bark give rise to yeast-like buddings after 48 and 52 hours at 

 temperatures under 28°C. and 16°C. respectively. 



2. In a decoction of oak bark, the formation of yeast-like buddings 

 is very active. 



3. Basidio-spores do not perish in a temperature of 0°C. in a 

 period of 24 hours. 



4. Basidio-spores standing 2 hours at 0°F. do not lose their 

 germinating power. 



5. Basidio-spores often give rise to mycelium directly in distilled 

 water. 



III. On the Mycelium of the " White Judas'-Ear " 



The mycelium of this basidiomycetes may likewise be used in the 

 propagation and the following are the results of investigations : — 



1. The mycelium of the " White Judas'-Ear " perishes when dried. 



2. The Mycelium does not perish at a temperature of 0°C. 



3. The mycelium perishes when kept at a temperature of 0°C. 

 for 5 hours. 



IV. Notes on the Culture of the " White Judas'-Ear " 



The fruit-body of the "White Judas'-Ear" is a substance which 

 appears after a rain or on wet season so that the collection of spores is 

 particularly difficult. Owing to the difficulty, propagation by means of 

 mycelium was first tried in April, 1907. The rotten billets of Konara 

 (Quercus glandulifera Bl.) grown with this mushroom was turned into a 

 soft mealy substance adding sufficient water. This was inoculated on 

 Konara billets which had been cut in the previous September, and were 

 carefully kept. About July, the first fruit-body appeared and after that 

 time both in spring and autumn fruit bodies appeared. The fruit-body pro- 

 duced on the same billets in June was made into meal with water and was 

 inoculated on Konara and Shide (Hornbeam) wood previously stelirised. 

 The billets so treated were piled on heaps with other billets grown with 

 the " White Judas'-Ear " produced in the Institute. Again on Konara
