CHAPTER XI 
FUNGI 
Tue Fungi are Thallophytes which do not contain chlo- 
rophyll, consequently do not possess the power of making 
their own food. They must obtain it from some source out- 
side themselves, and with different kinds of Fungi the 
source of food materials is subject to great variations. The 
structures of various Fungi are developed with reference to 
the different ways in which they obtain their food, as well as 
with reference to their peculiar problems of reproduction. 
LESSON XLI 
Mucor, a mold 
General study.—A few days before this plant is to be 
studied, some damp bread, over which a little old mold has 
been rubbed, should be placed under a glass cover. This 
will almost always produce an excellent growth of material. 
Abundance of material can usually be found upon damp 
bread or fruit that has been neglected for a few days. 
Make a careful observation of the plants, noting the 
gray mat upon the bread and the stalks that arise from it. 
Frequently upon these upright stalks there are sporangia. 
Examine to see whether the mat penetrates the bread. The 
woven mat is the mycelium, a single thread of which is a 
hypha. 
Details of vegetative structures—Mount some material 
from which the surplus bread has been carefully removed. 
Study the general structure of the mycelium. Study the .
