ASCOMYCETES 381 



place by the sprouting process described, though they may retain the 

 power of germinating for a longer period. 



This cell-increase by sprouting is, as has been seen, by no means 

 confined to Saccharomyces, but occurs in other groups of fungi (e.g. 

 Mucor), and the special character which entitles them to this place in 

 the classification of fungi is the production of asci, which they share 

 only with the Ascomycetes. They may therefore be regarded as much 

 degraded Ascomycetous forms— the other alternative, that they are early 

 forms from which typical Ascomycetes have developed, being disposed 

 ■of by the establishment of the connection of this great group with the 

 Phycomycetes as already described.
