mycelium indistinguishable from that found in other cases. No 
Botrytis appeared. The peculiarity of this form was that the 
sclerotia which were rather sparingly produced on the plants, 
were quite large and thick, much more so than in the ordinary no- 
botrytis type. In cultures numerous large, well-formed sclerotia 
appeared, some being an inch 
long and thick and solid (fg. 
41,and text fig. r a). These 
sclerotia could be grown by 
the quart on suitable media, 
dishes of prune bread being 
especially favorable. Their 
development is similar to that 
of the smaller ones in the last 
type described. Beginning as 
a white, harder spot in the 
mycelium they gradually 
enlarge, becoming, when ma- 
ture, black and hard. They 
have no connection with the 
substratum, being imbedded 
in the mycelium and easily 
separated from it. During 
their formation drops of a 
clear liquid usually appear on 
. the surface, and in old cul-

Fic. 2.—Sclerotia and apothecia of lium often become incrusted 
wae Denies: slightly reduced. with rod-shaped crystals of 
calcium oxalate. In cultures 
and on diseased plants organs of attachment are very abundant 
and entirely similar to those already mentioned. 
When placed on wet sand these sclerotia soon began to throw 
up slender stalks, usually several from each, which expand into 
trumpet-shaped Peziza apothecia. These bodies varied some- 
what in size and shape, as shown by the typical forms in text fig. 2»
