5. Alcoholic Extract. 



As far as my knowledge goes, the percentage of the sub- 

 stances soluble in alcohol is higher in the spores than in the 

 mycelium of fungi, as the following table shows :

It is probable that such substances as mannitol are ac- 

 cumulated in the spores as reserve materials, which are soluble 

 in alcohol. 



Finally, I give in the following table some figures showing 

 relations regarding to the composition of the spores, the pollen- 

 grains and the seeds of some plants : 



Penicillium-spores were analysed by Cramer, its mycelium by Marschall and the 

 pollen-grains by Planta, as mentioned before.
