hyaline. The edge varied from entire to undulate, frequently 

 thin and spreading. Internal structure, finely to coarsely granular 

 to grumose, often filamentous or tioccose ; commonly nucleated. 

 Medium strongly fluorescent. 



Strain CXV. — Punctiform to round and irregular, typically 

 becoming ameboid spreading, frequently nucleated, somewhat 

 raised to convex, becoming effuse or hyalin. The ti\ge was en- 

 tire to undulate or broken. Buried colonies irregular with spiny 

 processes. Medium not fluorescent. 



Strain CXL. — Round to irregular, raised, smooth, entire to 

 broadly undulate, sometimes broken. Microscopically; finely to 

 coarsely granular, grumose towards the center and commonly 

 showing irregular lines, being more or less floccose or curled. 



Strain CXLV. — Round, raised to convex, smooth with the 

 edge entire to curled. Microscopically; finely to coarsely gran- 

 ular, becoming grumose ; frequently floccose or curled. 



Strain CXLJ'III. — Macroscopically ; round, smooth, raised. 

 with edge thin, entire to undulate. Microscopically; finely to 

 coarsely granular or grumose, filamentous and curled to floccose. 

 Medium strongly fluorescent. 



Strain XXX I 'I. — Macroscopically; round, smooth, raised, 

 entire to thin and undulate, frequently becoming effuse. Micro- 

 scopically ; finely to coarsely granular, grumose, filamentous and 

 curled to floccose; sometimes the interwoven chains of cells sug- 

 gested an anthrax colony. Colonies were often surrounded by 

 a thin transparent zone with an undulate edge. 



Strain LI. — Macroscopically; round, irregular to ameboid, 

 smooth, raised with edge entire to undulate. Microscopically; 

 nucleated, finely to coarsely granular, becoming grumose towards 

 the center.
