THE EXAMINATION OF PLATE CULTURES 35 
Ameboid: very irregular, streaming. 
Myceliotd: a filamentous colony with the radiate character 
of a mold. 
Filamentous ; an irregular mass of loosely woven filaments. 
Floccose: of a densely woolly structure. 
khizoid: of an irregular branched, rootlike character, as 
in Bact. mycoides. 
Conglomerate: an aggregate of Solontes of similar size and 
form. 
Toruloid: an aggregate of colonies like the budding of the 
yeast plant. 
Rosulate: shaped like a rosette. 
. Detailed character of surface. 
Smooth: surface even, without any of the following dis- 
tinctive characters. 
Alveolate : marked by depressions separated by thin walls, 
so as to resemble a honeycomb. 
Punctate ; dotted with punctures like pin pricks. 
Bullate: like a blistered surface, rising in convex promi- 
nences, rather coarse. 
Vesicular: more or less covered with minute vesicles, due to 
gas formation ; more minute than bullate. — 
Verrucose: wwartliles, bearing wartlike prominences, 
Sguamose.: scaly, covered with scales. 
Echinate: beset with pointed prominences. 
Papillate: beset with nipple- or mamma-like processes. 
ugose: 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. 
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.
