Amoeboid: Very irregular, streaming (Fig. 141, b). 



Mycelioid : A filamentous colony, with the radiate 

 character of a mould (Fig. 141, c). 



Filamentous : An irregular mass of loosely woven 

 filaments (Fig. 142, a).

 i . General Character of Surface as a Whole: 

 Flat : Thin, leafy, spreading over the surface (Fig. 



143, ) 



Effused: Spread over the surface as a thin, veily 

 layer, more delicate than the preceding. 



Raised: Growth thick, with abrupt terraced edges 

 (Fig. 143, b). 



Convex: Surface the segment of a circle, but very 

 flatly convex (Fig. 1 43 , c) .
