Hypliae septate, 1-4.5/* iu diameter, not inoniliform. Conidiophores lateral, 

 septate, 7.5 x 54-75/a with tufts of spores agglutinated by a mucilage. Spores 

 thick-walled, 5/* in diameter, about thirty in a group, the whole resembling 

 a cauliflower on its stalk. 



On glucose agar, growth at first white and dry, later turning grayish rose 

 and developing a powdery white efflorescence. Giant colony, grown on glu- 

 cose, shows at first a central yellowish ray surrounded by white hyphae and 

 bordered by a circle of radiating, hyaline hyphae. The median ray eventually 

 disappears, the colony becomes gray or rose gray in color, the color deepening 

 and becoming accentuated in time with the filaments growing up the glass. 

 On "poor" Sabouraud agar, colonies small and yellowish, later becoming dry 

 and pale with filaments climbing up the glass. On potato glycerol, colonies 

 deep yellow, later becoming deep orange, covering the medium with a loose, 

 silky velvet, afterward becoming granular, and then covered with a white

powder. On sweet potato, there forms a loose white velvet, which later be- 

 comes a thin gray membrane, spotted with points of yellow or rose red or dark 

 green, eventually long, slender, loose filaments climb up onto the glass. A 

 greenish pellicle forms on the water of condensation and culture and is finally 

 green, covered with white filaments up to 2 cm. long. In glucose broth, a 

 slight cloudiness develops, then gelatinous fiocci filling the liquid which be- 

 comes viscous with a hyaline veil at the surface. This pellicle finally becomes 

 dotted with white.
