PUFF BALLS. 
We must call the attention of Mycologists to two monographs, 
the one of the Lycoperdons, by Mr. G. Massee, in the “ Journal 
of the Royal Microscopical Society,” prepared with great care, 
and the examination of authentic specimens ; the other of the 
Geasters, by Dr. de Toni, in “ Revue Mycologique.” We regret 
to add that the latter has not been prepared with the requisite 
care, and unfortunately leaves the genus more confused than ever. 
Species are united which have no relation to each other, and 
assumptions made where the types have not been consulted to an 
extent which, to our minds, renders the monograph valueless. The 
time and space required to demonstrate this would be as great as to 
prepare a fresh monograph, and we are too fully employed, but the 
necessity for a thorough and practical monograph, based upon in- 
disputable data, is more urgent now than ever.
