Acknowledgment. — To Superintendent M. E. Haul of Chillicothe. and 

 to Dr. H. S. Pepoou of Chicago, we extend thanks for the photos used in 

 making the cuts for this Xuniber. All of the species are common ones and 

 may perhaps be recognized when found. The tigure of the Jack-my-Lantern 

 (Fig. 55) will be supplemented in a future Xo. by a photo of a single specimen 

 natural size — and this very comuKm species then could not l)e mistaken. 

 This is one that should be learned at once, for attractive as it is. unfortu- 

 nately it is not an edible species. 



Am-a-ni'-ta Again. — The figures given in Bulletin Xo. 14 are to l)e most 

 carefully studied. Especial attention was called to the presence of n rol'-ra 

 (usually conspicuous) and the an'-itulus — these terms being also there ex- 

 plained. The vol'-va forms a H)iirer.'«(J veil in the young stage, that is. a layer 

 of thin tissue that entirely envelopes the young plant; it is more or less//Te 

 from the cap. When the veil is attached and inseparable, not easily dis- 

 tinguishable, the botanists say it is "concrete" with the pileus.
