Lycoperdon Peckii Morgan. A form 



Plates 53 and 113 



Plants shaped as in L. gemmatum, the distinct stalk up to 3 cm. long; the mycelium 

 ropy; peridium about 1.5-3.8 cm. broad, covered with tapering spines about 1-1.5 mm. 

 long, which as the plant grows split at base into 2-4 parts which remain united at their 

 tips and are easily rubbed off, leaving pale, smooth, circular spots which are surrounded 

 by minute granular warts and dots; color of the longer spines in youth and until near 

 maturity a delicate and pretty purplish lavender, at maturity changing to buffy brown. 

 Toward the base the spines become more slender and hairlike and are more obviously 

 intermingled with granular matter. Except for the lavender color of the upper half, 

 the plant until near maturity is nearly white. Subgleba composed of rather small cells 

 and occupying about a third of the plant. 



Spores (of No. 5749) olivaceous brown, spherical, 3.6-4.4/j thick, with a small oil 

 drop and a short pedicel, the wall obscurely dotted (pitted or minutely warted) and 

 appearing faintly striate radially in optical section; surrounding the spore is the thin 

 hyaline layer that is found in most Lycoperdon species. Capillitium threads very 

 slightly branched, up to 6/x thick and tapering to delicate tips. 



We have compared our plants with a collection in the Albany Herbarium from 

 Forestburg, N. Y., collected and determined by Peck and find them the same in appear- 

 ance, surface characters, spores and capillitium. The species (at least in so far as our 

 collections go) is easily distinguished in the fresh state before maturity by the lavender 

 color, a character not mentioned by others; in the mature and dry state it is distin- 

 guished by the ochraceous or buff color, by compound spines with flaring bases and 

 delicate, cohering tips, by granular matter between the spines, and by the small, dotted 

 (not obviously warted) spores with distinct pedicels. When the spines fall away they
