Iiycoperdacese 



spores and capillitium greenish-yellow, then brownish-olivaceous ; the Lycoperdon. 

 threads with the main stem about as thick as the spores, and long 

 tapering branches. Spores globose, minutely warted, 4-5/* in diameter, 

 mostly with a short pedicel. 



Peridium 1-2 in. in diameter and 1-2 in. in height. A very pretty 

 puff-ball with a silky shining coat. Morgan. 



New York, Peck, 49th Rep. ; West Virginia, Pennsylvania, New 

 Jersey. Ground in woods. August to October. Mcllvaine. 



Not frequent though general. It is good but must be young. 



L. calyptrifor'me Berk. hood-shaped. Peridium about 6 lines 

 high, 3-4 in. broad, ovate or subconical, sessile, whitish, furfuraceous 

 with minute warts or spinules ; capillitium and spores olivaceous or yel- 

 lowish-olivaceous. Spores smooth, 4/x, 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 later- 

 ally flattened, instead of papilliform,as required by theoriginal description 

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

 characters. The plant is very distinct from all our other species by its 

 small size and ovate or conical shape. Peck, $2d Rep. N. Y. State Bot. 



Cortex of minute spinules, scales or granules. Lignatile. 



L. pyrifor'me Schaeff .- pear-shape. (.Plate CLXXI, p. 602.) Plant 

 6-15 lines broad, 10-20 lines high, generally cespitose, obovate, pyri- 

 form or turbinate, sessile or with a short stem-like base, radicating with 

 white branching and creeping root-like fibers, subumbonate, covered 

 with very minute subpersistent, nearly uniform warts or scales, often 

 with a few slender scattered deciduous spinules intermingled, pallid 

 dingy-whitish or brownish ; capillitium and spores greenish-yellow, then 

 dingy-olivaceous, columella present. Spores smooth, 4^ in diameter. 

 Edible, but not well-flavored. 



Decaying wood and ground both in woods and cleared fields. Very 

 common. July to October. Peck, 32d Rep. N. Y. State Bot. 



Common the world over. Growing on logs, stumps, ground containing 

 decaying woody matter. So dense in its clusters at times as to present 

 an impervious surface. It is slightly acrid to taste and smell when raw. 



Edible. Tender and of second-class flavor when young; white
