MICROBIOLOGY 



Bullate: like a blistered surface, rising in convex prominences, 



rather coarse. 

 Vesicular: more or less covered with minute vesicles, due to gas 



formation; more minute than bullate. 

 Verrucose: wartlike, bearing wartlike prominences. 

 Squamose: scaly, covered with scales. 

 Echinate: beset with pointed prominences. 

 Papillate: beset with nipple- or mamma-like processes. 

 Rugose: short, irregular folds, due to shrinkage of surface 



growth. 



Corrugated: in long folds, due to shrinkage. 

 Contoured: an irregular but smoothly undulating surface, like 



the surface of a relief map. 

 Rimose: abounding in chinks, clefts, or cracks.

Fig. 35. Types of colonies: 1, cochleate; 2, amoeboid; 3, rhizoid; 

 4, mycelioid; 5, filamentous; 6, curled structure. 



3. Internal structure of colony (microscopic). 



Amorphous: without definite structure as below specified. 



Hyaline: clear and colorless. 



Homogeneous: structure uniform throughout all parts of the 



colony. 



Homochromous: color uniform throughout. 

 Granulations or blotchings. 

 Finely granular. 

 Coarsely granular. 



Orumose: coarser than the preceding, a clotted appearance, par- 

 ticles in clustered grains. 



Moruloid: having the character of a morula segmented, by which 

 the colony is divided into more or less regular segments.
