62 Synopsis of the Bacteria and Yeast Fungi. 



27 iL long, which produce secondary roundish or oval 

 daughter-cells, 5-6 ju. long. Spore-forming cells roundish 

 or oval; spores from 2 to 4 together, 2 ju, in diameter. 



(Fig- 63.) 



In the after-fermentation of wine, and fruit-wine, or 

 spontaneously fermenting beer. [The "caseous ferment" 

 of Pasteur ; may be obtained sometimes in English yeast.] 



85. S. apiculatus, Reess {I.e., p. 84). 



Carpozyma apiculaium, Engel. 

 Cells lemon-shaped, shortly apiculate at each end, 6-8 

 ju, long, 2-3 /A broad, sometimes slightly elongated, and, 



according to Hansen, 

 towards the end of their 

 growth becoming oval; 

 daughter-cells arisingonly 

 from the ends of the 

 mother-cell ; for the most 

 part soon isolated, rarely 

 united in small, scarcely 

 branched colonies. Spores unknown. (Fig. 64.) 



In the principal fermentation of wine, and in other 

 spontaneous fermentations. [On all kinds of fruit, stone- 

 fruits, etc., in must, and in certain kinds of beer.]

86. S. sphsericus, Saccardo (" Fungi Italici," fig. 76). 



Cells of various forms ; the basal ones (of a colony) 

 oblong or cylindrical, 10-15 /^ long) 5 /«■ thick; the 

 others round, 5-6 ju, in diameter, united in bent, branched, 

 often clustered families. Spore-formation unknown.
