EDITOR'S NOTES. 



In a Paris letter of July last Mr. C. G. Lloyd says : "There 

 has been so much changing of names lately in the Polyporii that 

 we feel it well to state our position in this regard. The most 

 and best systematic work on Polyporus was done by Fries. 

 His system and names have been in use for two generations, and 

 are familiar to all. We therefore feel that no attempt should 

 be made to change them, except in very exceptional cases. . . 

 As to the genera, the question is not so simple. The genus Poly- 

 porus is too large and should be broken up, but I feel that as 

 much of the old should be retained as possible, particularly the 

 four leading sections with which we are all familiar." I need 

 not add that Mr. Lloyd condemns very emphatically the work 

 that has been done the last few years in making new genera 

 of polyporoids. In fact we must admit that at the hands of 

 a number of competent mycologists the work here alluded to 

 has not found favor. 



We quote the above and allude to the situation there com- 

 mented upon, to emphasize the difference that obtains between 

 that case and the one presented by such work as is outlined 

 in the review in the first part of this No. of the Journal. To 

 Dr. Arthur's scheme it is expected that some, possibly many, 

 will object; for here too is "a vast array of new names." When 

 we read "Pyropolyporus," "Cianoderma," "Coriolus," we get no 

 new idea, at least no new information is suggested. But when 

 we are presented with "Uredinatae," Pucciniastratae," "Chryso- 

 myxatae," "Cronartiatae," we must form a new conception, and 

 look from a new point of view. So also the "vast array" of 

 new genera or new meaning in old genera, as "Cronartium," 

 "Cerotelium," "Cionothrix," "Alveolaria," "Baeodromus," "En- 

 dophyllum," and Pucciniosira," stand in each case for advanced 

 views based on advanced knowledsfe and new valuations.
