Die Parasiten der Infectionskrankheiten. 31 
surrounded by many filaments of ripe cladosporium with long spore 
chains. 
Upon dry vegetable matters, like disinfected cork or potatoes, 
I have seen the cells of the fungus (spores) germinating in the 
same manner as on the lemon; but instead ot the coniothecium 
(in every one of my cultivations of these spores), the filaments bore 
the truc schizosporangia of which the following figures give you 
an idea. The schizosporangia are formed on the ends of bran- 
ches, not interstitial like the coniothecium. The fruits are of very 
different forms, and of a dark brown color; they are scarcely to 
be seen by the naked eye, but with a lens you see black spots 
on the cork or potato, and these spots are covered with fruit- 
bearnig filaments. On the potato the schizosporangia occasionally 
do not ripen, and in this case, if the potato is moist, the unripe 
or mucor-form appears. 
Notwithstanding the great similarity of the coniothecium 
syphiliticum and the species here described, they are entirely diffe- 
rent. I tried to cultivate the syphilis fungus at the same time 
(on the same days that I was cultivating the spores from disea- 
sed cattle), and upon the same substances, but never got the 
schizosporangia under the same circumstances as those observed 
in the cultivation of the fungus from the infected cattle in Ame- 
rica. Our Coniothecium from the bile of the infected animals was 
unknown till now, and for this reason, allow me to give it the 
name of Coniothecium Stilesianum, in honor of the first disco- 
verer of the parasite vegetable-cells in the blood and bile of the 
infected cattle. 
Of this Coniothecium, we have now succeeded in getting all 
the ripe (nature) and unripe (immature) forms. 
1. Type-form (anaerophytic spores) ripe: Coniothecium Stilesia- 
num, unripe: Oidium like filaments. 
Schizosporangia (Septosporium according, to the ancient sy- 
stem); unripe*): Mucor Coniotheeii Stilesiani. 
3. Aérophytic form ; ripe: Cladosporium; unripe: Oidium -like 
filaments **).

**) Der in Klammern beigefüste Zusatz scheint auf einem Missverständ- 
niss zu beruhen, ebenso das: Oidium-like filaments; es muss heissen: Penicil- 
lium-form.
