Homma: On the '•Kirkosiniwiiiy" of, Ekvsiphaceae- 6t 



RKSU'MK 



It is a well known fact tliat the so-called "I-'ibrosin-hody" a reserve material, 

 is containcil in e\ery organs of the genera belonging toi the family Eyysi- 

 phaccae. In the present investigations, its staining, cnzymic and chemical re- 

 actions were tested. The writer came to the conclusion that the "iMbrosin" 

 seems to be a ,?-VI-carbohydrate containing N, and its molecular formula may 

 be (CcHjoOj)nNH2. The "Fibrosin" assumes not only a special form, but 

 very often granular in its conidium, eonidiophore, ascospore and mycelium.
