THE FUNGI Be | be 
(spore cases). All of the fructifications, however, produce Spores. 
During wet weather amoeboid protoplasts (swarm spores) escape 
from the spores, each developing a single celium and moving 
actively about. In time the cilia disappear and _ these 
swarm spores coalesce in smaller then larger groups to form a 
plasmodium.

Crass III.—Eumycetes (True Funct) 
The True Fungirepresent a large class of chlorophylless plants 
in which are included plants ordinary called fungi, such as the 
molds, water-molds, yeasts, blights, mildews, rusts, smuts, toad- 
stools, puffballs, etc. In nutrition, they are either saprophytes 
or parasites or may be adapted to both modes of existence. Most 
of them have a vegetative body called a mycelium consisting of 
filamentous hyphe. This class is subdivided into the following 
sub-classes: 
Sub-Class I. Phycomycetes or Alga-like Fungi—molds, 
water-molds, blights, mildews, rots. 
Sub-Class II. Ascomycetes or Sac-Fungi—yeasts, blue and 
green molds, powdery mildews, cup-fungi, morels, ergot, etc. 
Sub-Class III. Basidiomycetes or Club-Fungi—smuts, rusts, 
mushrooms, puff-balls, earth stars, etc.
