162 IMPORTANT VARIETIES OF FISSION-FUNGI. 



were cultivated in our institute could be easily designated 

 as Sarc. aurantiaca ; moreover, we can not differentiate 

 Sarc. aurea Mace, Sarc. aurescens fusca and fusees- 

 cens Gruber from Gruber's description. 



Sarcina cervina (Stubenrath). 



(Plate5, i.) 



Gelatin plate colonies, macroscopically, at first are whitish, after 

 four to five days pale brown, somewhat moist, slowly becoming sur- 

 rounded by a zone of liquefaction. Magnified sixty times : with 

 coarsely granular projections, gradually breaking up at the edge into 

 coarsely granular, cloudy masses. Gelatin stab superficial growth 

 small, pale brown, very slowly sinking in. Stab faint, thread-like, 

 finely granular. Agar plate similar to that on gelatin. Agar 

 streak broad, moist, elevated, yellowish-brown (5, i). Potato cul- 

 ture brownish- white. Magnified one thousand times, it is seen to 

 consist of mostly irregular bales of packets, which appear a light 

 brownish color. This variety was once isolated from the gastric con- 

 tents in a case of carcinoma. 



Sarcina erythromyxa (Krai). 

 (Plate 5, in.) 



Literature. Krdl (list of the bacteria handed over); Micr. eryth- 

 romyxa Overbeck (Nov. Act. der Leop. -Carol, Bd. 55, No. 7, 1891). 

 Good description by Zimmermann (n, 70). 



Magnified one thousand times, usually only cocci, diplococci, and 

 tetrads ; only once did we obtain upon hay decoction a beautiful for- 

 mation of regular bales of packets. 



Upon gelatin plates (natural size) the colonies are at first a lively 

 greenish color, then beautiful carmine- to vermilion-red, and moist. 

 Magnified sixty times, almost without granulation ; at the edge the 

 red colonies are usually transparent and finely notched-. There is no 

 liquefaction. Gelatin stab, agar stab and streak, and potato cultures 

 gradually develop as an intensely red, shining, rather spare growth. 

 Upon milk a red growth forms on the surface, and the milk slowly be- 

 comes clear without preceding coagulation. Bouillon becomes cloudy 

 with a coarse, crumbly sediment and at times a pellicle. Moderate 

 production of acid on grape-sugar bouillon. 



Sarcina rosea. J. Schroter emend. Menge (B. vi, 596) 

 and Zimmermann (ii, 58). 



The description of this organism (5, vi) coincides absolutely as re-, 

 gards its growth upon all nutrient media with that given for the Micr. 

 roseus (p. 190); the illustrations in Plate 11 also are as good for the
