Growing on the ground in woods. New York, Peck ; Mar}-- 

 land, y^w^^. Peridium 1-2 inches in diameter and 1-2 inches 

 in height. This is L.gcmviatum var. hirium of Peck's U. S. 

 species of Lycoperdon. 



^. Cortex of stout spines 7vJnch fall azcay and leave a 

 tomcntose or Jurjuraceous surface to the ijiner 

 peridium. 



15. L. ExciPULiFORME, Scop. Peridium turbinate, de- 

 pressed above, plicate below and contracted into a more or 

 le.ss elongated base. Cortex of large stout spines, conver- 

 gent above, becoming smaller downward, which at length fall 

 away, leaving a tomentose surface to the inner peridium. 

 Subgleba occupying one-half or more of the peridium; mass 

 of spores and capillitium greenish-yellow, then brownish- 

 olivaceous; the threads about as thick as the spores, scarcely 

 branched; spores globose, minutely warted, 4-5 mic. in 

 diameter. 



Growing on the ground in meadows and woods. Pennsyl- 

 vania, North Carolina, Scfnveinitz ; Canada, Saccardo. Perid- 

 ium 1-2 inches in diameter and 1-4 inches in height. 



16. L. sEPARAxs, Peck. Peridium broadly obovoid, often 

 much depressed, plicate underneath, with a cord-like root. 

 Cortex a dense coat of stout white convergent spines ; after 

 maturity these peel off in flakes or patches, revealing a thin 

 furfuraceous layer of minute yellowish to pale or dark brown 

 .scales, covering the surface of the inner peridium ; these also 

 gradually disappear, leaving a pale, smooth, shining surface. 

 Subgleba broad, occupying about a third part of the peridium, 

 definitely limited above ; mass of spores and capillitium pale 

 to dark brown ; the threads variable in thickne.ss, but some of 

 them thicker than the spores, scarcely branched ; spores glo- 

 bose, even, 3.5-4 mic. in diameter. Plate II, Fig. i. 



Growing on the ground in pa.stures and meadows. New 

 Kngland, Frost; New York, Peck ; South Carolina, Atkinson : 

 Ohio, A/or i^ an ; Wisconsin, Trelease. Peridium 1-2 inches in 

 diameter and about i inch in hciglit. This is L. separans of 

 Peck's 26th N. Y. Report and L. W^riolitii var. separans of 

 Peck's U. S. species of Lycoperdon. It is also no doubt A.
