Protoascineae. 



Specimens of a number of Saccharomyces species are found in Ro- 

 strup's herbarium, supplied by Mr. Ove Rostrup. Concerning their 

 classification, biology etc. the papers of E. C. Hansen, Klecker, Sch0- 

 ning, Grenlund, Alf. Jergensen, Orla Jensen and others may be re- 

 ferred to (A list of the literature is found in Kleckers (06 a 6^ b) 

 and Lindners (05) papers). A number of the species are divided into 

 numerous subspecies or races, more on account of their effect (on beer 

 and wine) than according to morphologic characters. Concerning their 

 localities very little information is found in literature as they are only 

 studied in breweries and laboratories.
