Quite recently the author, also JUST CHR. HOLM, JOHAN- 

 OLSEN, and others, have found Dematium species with 

 endogenous spore-formation ; from these spores develop bud-

ding fungi, also producing endogenous spores, and consequently

H. STOECKLIN found in the filaments of O'idium albicans 

 (Saccharomyces albic.) a similar endogenous spore-formation ; 

 budding fungi were developed from the spores.
