72 Thirty-second Report on the State Museum. 



are found in one place. The warts are very minute, and easily overlooked. 

 They have a granular or almost mealy appearance, and, when old, usually 

 become blackish. At first the capillitium and spores appear to have a sul- 

 phur-yellow color ; but when fully mature, if the capillitium is cleared of the 

 spores, it is seen to be much darker. There appears to be a slight depression 

 in one side of the spore, so that, when viewed in a particular direction, it 

 appears flattened or depressed on one side, although viewed in a different 

 direction it may appear globose. 



Lycoperdon calyptriforme Berk. Conical Puff-ball. 



Peridium about 6'' high, 3' -A" broad, ovate or subconical, sessile, whitish, 

 furfuraceous with minute warts or sipinules ; capillitium and spores olivaceous 

 or yellowish-olivaceous ; spores smooth, .00016' in diameter. 



Moss-covered rocks. Very rare. Adirondack Mountains. August. 



I have met with this very small and rare species but once, and then but 

 two specimens were found. In these the apex was compressed or laterally 

 flattened, instead of papilliform, as required by the original description of 

 the species ; but in all other respects they agree well with the specific charac- 

 ters. The plant is very distinct from all our other species by its small size 

 and ovate or conical shape. 



In closing this report, grateful acknowledgments are rendered to those bot- 

 anists whose names already appear in the preceding pages, for their kind coop- 

 eration in the investigation of our flora, and for their generous contributions of 

 specimens. 



When no name is added to the station or stations herein given, the plant has 

 been found therein by the writer. Dates signify the time when the specimens 

 were collected or the plants observed. 



Respectfully submitted, 



CHAS. H. PECK.
