PLATE LI
Alkaloids.

1. Penicillium, mycelium from 0.0065 per cent solution atropin sulphate,
showing stunting and distortion.

2. Penicillium, mycelium and fructification from 0.1625 per cent solution
cocain hydrochlorate, showing stunting and distortion.

3. Penicillium, mycelium from 0.1625 per cent solution morphin sulphate,
showing stunting and distortion.

2. Alternaria, showing h}-phae with reduced plasma, from 0.01 per cent
solution.

3. Oidium, mycelium from 0.01 per cent solution, showing disorgani-

PLATE LIV
Carbolic acid.

1. Penicillium, mycelium from 0.1 per cent solution, showing swelling,
specially of germinated conidia, ir^creased number of septa, and dis-
organization of the plasma.

2. Alternaria, mycelium from 0.02 per cent solution, showing strong dis-
organization.

3. Oidium, hj^phae and oidia from 0.1 per cent solution, showing swelling
in some oidia.

PLATE LVII
Mixturcr.

1. Conidia from solution containing 0.75 per cent acetic acid and 0.1 per
cent sodium benzoate. The result appears as a combined action, both
agents causing swelling and disorganization.

2. Hyphae and conidia from solution containing 16.25 per cent sugar,
3.75 per cent salt, 0.375 per cent acetic acid, and 0.05 per cent sodium
benzoate. Only the action of the acetic acid and sodium benzoate is
seen in the swelling and disorganization.

3. Hyphae and conidia from solution containing 3.75 per cent salt, 0.375
per cent acetic acid, and .05 per cent sodium benzoate. In this cul-
ture the action of the three agents is noted in the stunting of some and

• the swelling and disorganization of others.

PLATE LVIII

Penicillium, the length of time required for germination is given in the
table on results of germination tests.

1. Control, young.

2. Control, 590 days, showing hazy appearance and somewhat stunted
fruiting heads.

3. Salt solution, 15 per cent. The mj^celium shows decided stunting, the
effect persisting.

enlargement.

2. Distilled vinegar, 1 per cent, 380 days. The hyphae show stunting.

disorganization.

2. Borax, 0.2 per cent, 423 days. The effect was mainly stunting.

3. Sodium salicylate, 0.2 per cent, 590 days. Swelling and disorganization
shown.
