I4 ENTOMOPHTHORACEAE 



phores simple or branched, bearing one-celled conidia ; sporangiophores simple, spo- 

 rangia with a small columella. 

 A single genus Choanophora 9: 339, S. 131 



Subfamily Chaetocladiae 

 7: 220, S. 131 



Mycelium parasitic on species of Mucor ; propagation by conidia, sporangia lack- 

 ing, conidia arising on short side branches ; zygospore arising directly from the fused 

 gametes. 

 A single genus Chaetocladium 7: 220, S. 131 



Subfamily Syncephalidae 



7: 225, S. 132 



Conidia in chains on short basidia borne on the end of the sporophores ; zygo- 

 spores arising as an outgrowth from the tips of the suspensors after conjugation. 



I. Sporophores not swollen at tip Piptocephalis 7: 225, S. 132 



II. Sporophores swollen into a head at tip

Family 9. ENTOMOPHTHORACEAE 



Schroeter 134, 7: 280, 9: 349, 14: 43;, 16: 388, 17 : 510 



Mycelium usually well-developed, tubular or filamentous, mostly parasitic or en- 

 dozoic, rarely saprophytic, at first one-celled, then septate ; propagation by one-celled 

 conidia terminal on one-celled clavate conidiophores ; zygospores globose.

Order 5. VAUCHERIALES 



Unicellular, multinucleate, saccate or filamentous algae and fungi ; propagation 

 by zoospores or conidia ; sexual reproduction in the three fungous families by un- 

 like gametes, produced in antherids and oogones.
