 this species. The curious lobing of the Ivs. on the 

 young growth is shown in the upper spray of Fig. 1433. 

 the nearest approach to this lobing is in the Japanese 

 {Moms Japonica), and this affords another of those 

 interesting parallelisms which exist between the Jap- 

 anese and eastern American tioras. The red Mul-

 immense numbers of spores, a fact which accounts for 

 their presence everywhere, in the air, in dust, and on all 

 exposed bodies. As a rule these fungi are not directly 

 injurious to plants; they are normally saprophytes and 

 perform a great service in disorganizing organic matter 

 which would otherwise accumulate on the earth. A

 humble green plants of the crypto-

 with distinct stems and foliage 

 leaves. In North America there 

 are about 1,200 species, distributed in numerous families 

 and four orders. They have solitary, mostly stalked 

 spore-cases or capsules arising from the apex of a leafy 

 stem (Fig. 1434) . The capsule is covered with a thin cap
