h<iud. Some will doubtless take issue with the failure to include references 

 to large lists of new species described by various authors. These have not 

 been included, except where a generic revision is included in the paper, or 

 where the genus is a large one, with many new species systematically arranged. 

 A word must be said as to the names employed for the classes, orders, 

 etc. The familiar classes — Phycomyceteae, Ascomyceteae and Basidiomyceteae 

 and the "form class," Fungi Imperfecti, will be recognized by every one. 

 Following C. E. Bessey, the Rusts and Smuts are considered to be sufficiently 

 distinct from the Basidiomyceteae (although perhaps more closely related to 

 them than tothe Ascomyceteae) to be raised to the dignity of a separate cla.ss, 

 the Teliosporeae. Following many investigators, the Synchytriaceae are con- 

 sidered as being degenerate Chlorophyceae of the class Protococcoideae, and 

 not related to the Phycomyceteae. Ordinal names are all based upon a genus 

 included in that order and end in — ales. Family names are always based 

 upon a genus within the family with the ending --aceae. However, in listing 

 the contents of general works, the names there used are retained.
