108 A MANUAL OF THE PENICILLIA 



descriptive sheet elaborate enough to include all observations that may- 

 prove useful in diagnosis. A sample descriptive sheet is presented below. 

 Dimensions should be given as ranges established by the examination of 

 many units, not as precise measurements of individual cells or structures, 

 or as decimal values obtained by averaging a large number of separate 

 measurements. Colors should be cited as duplicating or approximating 

 specific plaques or tabs in some recognized color manual such as Ridgway's 

 •'Color Standards and Nomenclature" (1912), or as a particular range 

 covered by a series of such tabs.
