THE EDITOR NEEDS LITTLE SPACE. 



We print the conchuling^ portion of Mr. Kauffman's admirable 

 Key to the species of Cortinarius in this number. It can not 

 fail to be very useful to those who have the courage to attack 

 this difificult genus. Our species are so numerous that every one 

 can take a turn at the Key — but we will not be surprised if some 

 of the amateurs or even students later report to us that some 

 things are easier to master than this Key or the species of Cor- 

 tinarius. 



We are able to furnish an additional diversion also in the 

 presentation of matter that amateurs may not have thought of as 

 in the nature of "Mushrooms" — referring to the article on Moulds 

 by Superintendent Sumstine. Rut these are Eungi. and the word 

 Mycology includes this interesting group. We will be glad for 

 additional articles and notes by patrons of the P>i'LLn;Tix.
