285. Examination with the Magnifying Glass. — Study some of the 
larger and more mature patches and some of the smaller ones. Note: 
(a) The slender, thread-like network with which the surface of the 
bread is covered. ‘The threads are known as hyphe, the entire network 
is called the mycelium. 
(b) The delicate threads which rise at intervals from the mycelium 
and are terminated by small globular objects. These little spheres are 
spore-cases. Compare some of the spore-cases with each other and 
notice what change of color marks their coming to maturity. 
Fic. 199. — Unicellular Mycelium of a Mould (Mucor Mucedo), sprung 
from a Single Spore. 
a,b, andc, branches for the production of spore-cases showing various stages of 
maturity. (Considerably magnified.) 
286. Examination with the Microscope. —Sketch a portion of the 
untouched surface of the mould as seen (opaque) with a two-inch 
objective, then compare with Fig. 199. 
Wet a bit of the mould, first with alcohol, then with water. Examine 
in water with the half-inch objective and sketch a little of the mycelium; 
some of the spore-cases, and the thread-like stalks on which they are
