OPEGRAPHACEAE 

 Graphis scripta Ach. 

 Bark of trees and shrubs. Very common. 



The species of fungi are so numerous that it has seemed desirable to 

 indicate by name the larger groups in which the families are arranged. 



These depend upon the character of the fructification or of the part of 

 the plant immediately concerned in s|)ore production. The group 

 Hymenomyceteae, in which the spores are produced on specialized cells 

 or basidia seated on exposed surfaces, includes by far the greater number 

 of species and is placed first.
