EDITOR'S NOTES. 



This No. of the Journal is issued somewhat earher and the 

 size is less than usual, on account of the editor's contemplated 

 trip to Guatemala. The next No. may be correspondingly de- 

 layed by his prolonged absence. We regret also that no account 

 can at present be given of the mycological papers presented at 

 the New York Meeting of the A. A. A. S. and affiliated societies. 



In this No. we are concluding the installments of Professor 

 Morgan's monograph of the North American species of Lepiota. 

 The parts will be reprinted as a single pamphlet. This then, as 

 well as the North American species of Marasmius, by the same 

 author, will we are sure be welcomed by very many botanists. 

 Those interesting special groups can now be observed and studied 

 systmatically and advantageously — scarcely the case when the 

 literature pertaining to many of the species remained practically 

 inaccessable except perhaps to the specialist himself. 



As serving a similar purpose and likewise of special advantage 

 to the student of mycology — therefore it can be placed in the 

 same category, namely, the article we are giving this month by 

 Mr. Kauffman of the University of Michigan. His excellent 

 work on the species of Cortinarius. to which difficult and im- 

 portant group he is still devoting himself, will be keenly appre- 

 ciated by those interested in the Agarics. To the numerous other 

 contributors in the past we are equally grateful for important 

 articles — all of which in fact can justly be claimed as creditable 

 to American mycology. 



The Journal has set for itself the aim to index and in a 

 measure to represent the work of our mycologists — and inci- 

 dentally to give by brief notes some idea of the work in the 

 entire mycological world. In our scope we include monographic 

 articles of lesser or greater extent — and we expect to present 

 from time to time much work of the latter character.
