plant in its early stages and as the plant develops, breaking up into 

 ragged pieces which partly adhere loosely to the inner cortex or 

 finally fall away. Gleba brown, then purplish. Capilhtmm colored. 

 Spores large, 6-8 mic. rough. 



This is a rare plant in Europe and but one collection has reached 

 us. The peculiar cortex is well represented in some of the earliest 

 figures t Vittadini's figure shows the outer cortex too thick but the 

 specimen he left (see Plate 44, fig. 8) is very characteristic.

LYCOPERDON CUPRICUM (Plate 45). Plant with white, 

 fibrous roots. Sterile base of large cells. Cortex of fine, oppressed, 

 steiiate. connivent spines which fall away and leave the pcridium 

 smooth and polished. Columella prominent. Gleba dark umber.J 

 Spores medium, 4-5 mic. rough. 



The prominent character of the plant is the bright copper color. 

 After the spines fall the smooth polished surface appears like a sheet 

 of copper. There is one discrepancy with the original description. 

 The spines while small arc "discernible without a gln^s." The 

 appropriate name that Bonorden gave it leaves to my mind no doubt of 

 its reference. However, the color is poorly shown in Hollos' figure 

 which is unfortunate as the color is the character of the plant. A few 

 specimens of Lycoperdon atropurpureum we have with color of perid- 

 ium tending toward this species, which we refer to atropurpureum on 

 account of the purple gleba and larger, rougher, spores.

LYCOPERDON FUSCUM (Plate 45). Plants varying from 

 pear shape with scanty, sterile base to stalked with well developed 

 base. Cortex very minute stellate black spines, densely covering all 

 portions of peridium and very uniform in size. In old specimens they 

 partially fall off leaving the peridium at first reticulate finally smooth. 

 Peridium of a dark brown color. Gleba umber brown, very rarely it 

 takes a purplish tint. Spores medium 4-5 mic. rough. 



I accept this plant in the interpretation of Dr. Hollos as I kn >w 

 nothing of Bonorden's plant. It is rare in Europe but I have collected 

 it abundantly one season growing in woods over leaves at Eglon, W. 

 Va., in the United States. The dark color of the plant is noticeable, 

 and the minute, tufted black cortex spine characteristic.
