 1931, 1932) may be utilized. 



Consideration will be given to the morphology and develop- 

 ment of representative genera of each order as they are en- 

 countered in the brief accounts that follow. Special phyloge- 

 netic interest, however, centers on Gasterella liitophila, whose 

 fructifications range from 200 to 700 \i in diameter [Zeller and 

 Walker (1935)]. Its basidiocarps are uniloculate, indicating that 

 it is a primitive form.

Hymenogastrales 



This order includes perhaps 20 genera and more than 80 

 species of fungi having fructifications that develop in leaf mold 

 or more deeply submerged in the soil. Some remain subter-
