PHVLOGENY OF THE FUNGI 91 



production of numerous spores.' Erciiiascus also represents such a con- 

 necting form. From Eremascus by reduction forms like Endomyccs 

 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 LABOUXBENiACE.a: from red alga) ancestors, but another 

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

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

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

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

 family. Entomophthorace^.- The differentiation of types within 

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

 the various groups of PHYCOMYCETES and MYCOMYCETES.
