form closely adnate, and merely rimulose with age. Gleba quickly 

 turning dark reddish purple. Capillitium colored, branched. Sponcjj 

 large 6-7 mic., rough. 



This plant often occurs in sandy locations. In the typical northern 

 form the cortex is smooth and thin,' (Plate 56 fig. i) closely adherent 

 to the peridium and merely cracking with age. As the plant extends 

 South the cortex becomes rougher and thicker and the cracks m>R- 

 pronounced, (Plate 56 fig. 2) 'and finally in the extreme South, we 

 find forms in which the cortex first breaks into areas, (Plate 56 fig. 10) 

 then loosens up and finally falls away. The latter form we would call 

 by a separate name.

LYCOPERDON SUIJVELATUM* (Plate 56). This form 

 mentioned above is very close to Lycoperdon velatum of Europe ; in 

 fact, I am not sure but the exact plant grows in Europe, as Vaillant's 

 old figure (t. 16, f. 4), and Michelius' old figure (t. 97, f. 3) seem to 

 be exactly our plant. However, the plants I have seen from Europe 

 (Plate 44) have a more strongly developed base, a thicker cortex, and 

 the peridium develops a distinct, secondary cortex under the veiUf

LYCOPERDOX ATROPURPUREUM (Plates 42 and 57.) 

 Plants as they occur in the United States are usually small, obovate or 

 subglobose, from one half an inch to an inch and a half in diameter. 

 Cortex well developed, slender, cruciate spines, disposed to disappear 

 from the old specimens, leaving the peridium smooth. Sterile base 

 well developed of large cells, often purplish in color. Gleba at first 

 olive, slowly changing to umber and finally when fully ripe to dark 

 purple. Spores globose, rough, mixed with fallen pedicels, varying in 

 size from 5 mic. in the olive state to 6-7 mic. when fully ripe. 



We take one idea of the typical form of this plant as it occurs 

 in luiropc and is illustrated by Vittadini, the form with distinct slender. 

 :ruciate spines about 2 mic. long. It is frequent though not as common 

 as the timbrmum form.
