the slightest indication of endogenous form. In this respect it 
differs materially from the macroconidia of the Ceratocystis which 
Mr. Fairchild demonstrated was produced in the same way by ab- 
junction within the mother cell as above demonstrated for the 
microconidia. On the other hand, these spores are produced in 
chains of remarkable length and beauty in the Van Teighem cul- 
tures, there being sometimes 50 or more of the olive browh spores 
exceedingly uniform in size and holding together, even when the 
chains of spores have been distorted into extravagant shapes. 
That these two forms of spores belong to the same plant was 
demonstrated beyond question, because sometimes from the same 
hypha there was given off upon the right handa branch which de- 
veloped endogenously the microconidia, while a few micromilli- 
meters above or below and the opposite side a branch segmented 
into a chain of the macroconidia. 
By taking portions of the Cha/ara from beneath the surface of 
the pineapple it was easily demonstrated that spores were pro- 
duced from the subterranean filaments, which, while probably be- 
longing to the macroconidia, differed from them both in shape and 
color, they being much longer and narrower, and of an almost 
pale blue color, besides these were formed at the tip of the hypha, 
and usually singly or, at the utmost, in chains of two or three 
Spores. What was perhaps of more interest still is a form of 
spore agreeing in color quite closely with the macroconidia, 
but in size more nearly those of the hyaline microconidia. These 
were produced in long chains which easily fell apart and were as- 
sociated with both the other above-mentioned forms. At first 
_ Sight it would seem as if the hyaline, cylindrical, somewhat 
abrupt ended microconidia had become rounded and taken on a 
thicker cell wall and brown coloration ; but the formation of these 
spores is by ordinary fission of the hypha, and agrees in that 
tespect with the macroconidia. 
It would seem, therefore, that in our Cha/ara there are three 
quite well defined kinds of spores, not counting the ones that are 
Produced within the mass of the host, and as far as this goes it 
well bears out the specific name of the species, paradoxa. With a
