Parasitic by large or small haustoria or internal hyphae, in soil-inhabiting Rhizo- 

 pods or Nematodes. Family Zoopagaceae 



Main fungus body a thick spiral structure in the cell of an amoeba, conidia 

 borne on slender aerial hyphae. 

 Conidia borne singly at intervals on long aerial hyphae. Endocochlus 



Conidia borne in chains from erect aerial hyphae. Cochlonema 



Main fungus body a very much enlarged conidium on the outside of the body 

 of an amoeba, attached by dichotomously forked internal haustoria. 

 Conidia in long chains on erect aerial hyphae. Bdellospora 



Main fungus body an effuse mycelium, adhering to Rhizopods or Nematodes 

 and sending lobed haustoria into them. 

 Conidia in vertical chains on short lateral branches. On Rhizopods. 



Zoopage 

 Conidia single, sessile or almost so, upright on the creeping mycelium. On 

 Rhizopods. Acaulopage 



Conidia single on upright branches from creeping mycelium. On Rhizopods 



and Nematodes. Stylopage 



No conidia found but asexual reproduction by means of terminal, lateral or 

 intercalary chlamydospores. On Rhizopods and Nematodes. Cystopage 

 Main fungus body an extensive mycelium in the body of Nematodes. External 

 hyphae formed and bearing at right angles a number of short lateral coni- 

 diiferous branches which produce first a terminal conidium and then suc- 

 cessively in basipetal direction other conidia. Euryancale 



Key to the Families of Order Eccrinales

Resting spores at maturity with two nuclei. Family Arundinulaceae 



Resting spore at maturity with four nuclei. Family Eccrinaceae 



Amoeboid spores produced, also some resting spores. Family Amoebidiaceae
