PHYLOGENY OF THE FUNGI 91 



production of numerous spores.^ Eremascus also represents such a con- 

 necting form. From Eremascus by reduction forms like Endomyces 

 arose which in two diverging series connects various ascomycetous 

 fungal forms. One series shows sprout conidia, the other oidia. The 

 yeast series, the Exoascus series are thus connected. Some would have 

 us derive the Laboulbeniace^ from red algal ancestors, but another 

 opposing view is that these unusual fungi have had a Monascus-like 

 ancestor. The other branch leads to the Basidiomycetales where the most 

 primitive forms have not typical basidia, as in the Hemibasidii, and 

 which are connected with such primitive types as are included in the 

 family. Entomophthorace^.^ The differentiation of types within 

 these large phyla will be dealt with as we proceed with a discussion of 

 the various groups of PHYCOMYCETES and MYCOMYCETES.
