Explanation of plate 19 
The drawings were made with the aid of the Abbé camera lucida, from 
sections 5 yu thick and stained with Flemming’s triple stain, except figure 8 
which is a drawing from fresh material mounted in lacto-phenol. 
Zeiss microscope was used with a 1/12 inch oil immersion objective 
and a number 3 ocular. The magnification is about 1200 diameters. Fic. 8 
was drawn with the Zeiss objective D and number 3 ocular. 
Fic. 1. A broad multinucleated conidium characteristic of the species. 
Fic. 2. A young resting spore which probably arose by budding from 
the tip of a hyphal fragment. 
1G. 3. A young resting spore formed at the tip of a hyphal tube. 
Fic. 4. A young chlamydospore cut off from the tip of a conidiophore. 
A chain of four young spores. This material was not fixed well 
and shows considerable shrinkage. The protoplast in each spore is drawn 
away from the inner membrane, which is itself shrunken away from the 
spore wall. The outer thin membrane does not show and is probably closely 
applied to the slightly thickened spore wall. I am not certain that the upper- 
most and irregularly shaped spore belonged to the same hypha. This spore 
may have arisen from another hypha which lay across the first. 
Fic. 6. A chlamydospore showing numerous nuclei and granular 
threads connecting them. 
1G. 7. A chain of three chlamydospores connected by the old conidi- 
ophore tube wall. 
Fic. 8. A more mature resting spore. 
Fic. Two young rounded spores at the tips of hyphal filaments 
which, as in Fic. 2, probably arose by budding. The protoplasm contains 
many oil drops.
