Hyphx swollen, Llunt tips, protoplasm finely granulir, without 
cohesion, walls break with weight of cover-glass. Few sepia 
in some, in others prominent. Few side branches. Hyphe dis- 
organized when placed in water. 
Hyphe swollen, blunt tips thicker than older part, short thick side 
branches, finely granular protoplasm, not so badly disorganized 
as in cinnamon. 
Hyphe shrunken, distorted, tendency to develop conidiophores close 
to germinated conidia. 
Hyphe thin, tapering, protoplasm finely granular. 
Hyphe slender, tapering to threads, protoplasm reduced to lining 
of walls, coarse granules, many septa. 
Hyphz swollen, distorted, walls tough, protoplasm clear. 
Hyphe enlarged, blunt tips, few septa, short side branches, proto 
plasm finely granular. 
Hyphe and conidia swollen and distorted, no uniformity in forma- 
tion of septa, some hyphe, few, others many; protoplasm coarse- 
ly granular, filling tubes; walls break readily. 
Hyphe larger than in benzoate, more easily broken, distorted. 
Less swollen hyphe have less distortion and less disorganiza- 
tion. 
Hyphe short, distorted or long and swollen, blunt ends, proto- 
plasm clear, homogeneous or finely granular. 
Hyphe swollen, short thick side branches, blunt ends, protoplasm 
finely or coarsely granular. 
Hyphe as wide as germinated conidia, few septa, granular proto- 
plasm. 
Hyphe and conidia swollen, some of the conidia much elongated, 
hyphal ends blunt, few septa, protoplasm yellow, coarsely gran- 
ular, protoplasm and walls disorganized. 
Hyphe enlarged, few septa, protoplasm coarsely granular. 
Hyphe enlarged, some much swollen, slight distortion, clear, homo- 
geneous protoplasm, thick, stunted conidiophores. 
Hyphe enlarged, slight distortion, protoplasm yellow, finely gran- 
ular, dirty apnearance.
