LYCOPERDON PUSILLUM. 

 (After Morgan.) 



Lycoperdon. ( Plate CLXXV. ) at the base, white or whitish, brownish 



when old, rimose-squamulose or slightly 

 roughened with minute floccose or fur- 

 furaceous persistent warts ; capillitium 

 and spores greenish-yellow, then dingy- 

 olivaceous. Spores smooth, 4ft in dia- 

 meter. 



Ground in grassy places and pastures. 

 Common. June to October. Peck, 32d 

 Rep. N. Y. State Bot. 



West Virginia, Pennsylvania, New Jersey, North Carolina. Common. 

 Spring to autumn on ground in grassy places. Mcllvaine. 



Grows where almost nothing else will, and where I have despaired of 

 finding a meal of fungi, I could always find the ubiquitous L. pusillum. 



L. oblongi'sporum B. and C. oblong-spored. Peridium subglo- 

 bose, with a slender mycelial cord. Cortex a thin, whitish, furfuraceous 

 coat, drying up into minute persistent granules on the pale-brown sur- 

 face of the inner peridium. Subgleba nearly obsolete; mass of spores 

 and capillitium olivaceous, then brown; threads much branched, the 

 main stem about as thick as the spores, the branches tapering. Spores 

 elliptic, even, 5-6x3-4^, sometimes with a minute pedicel. 



Growing on the ground in dense woods. Wisconsin, Trelease. Perid- 

 ium %-i in. in diameter. This pretty species, previously known only 

 from Cuba, is indistinguishable from L. pusillum when immature, the 

 spores affording the only really characteristic feature. Morgan. 



L. cepsesf or'me Bull. onion-shaped. Peridium 

 globose or depressed-globose, plicate underneath, 

 with a cordlike root. Cortex at first a thin, white, 

 minutely furfuraceous coat, this soon becomes rimu- 

 lose and at length breaks up into small scales and 

 patches, which finally disappear from the pale or 

 pale-brown surface of the inner peridium. Sub- 

 gleba nearly obsolete ; mass of spores and capillitium 

 greenish-yellow, then pale-olivaceous ; the threads 

 very much branched, the main stem thicker than the 

 spores, the branches long and tapering. Spores 

 globose, even, 3.5-4^ in diameter, often with a 

 minute pedicel. 606
