with each observer, more or less. Recently, examining an 

 ascus of a Peziza, I found at one end a sporidium 24/i, at 

 the other 33)U,, in length. Notwithstanding the foregoing, 

 I deem spore measurement in connection with other spore 

 characters of great value in most cases. 



1 think, however, a paper specifically devoted to " Spore 

 variation" is one much to be desired. The matter should 

 be definitely determined whether spores of the same species, 

 from different regions do or do not vary, in considerable 

 degree, persistently.
