sometimes larger. Cap rather flat but irregular with pits, prolifera- 

 tions and asperities, at times with more or less distinct radiating 

 ridges, the center very rough like scoria with sharp points and pits, 

 minutely velvety, tomentose or smoothish in places, with faint struc- 

 tural zones; color a uniform cinnamon brown, deeper brown when 

 bruised. Flesh usually thin, very tough and firm except for a very 

 thin superficial felty layer, which tends to disappear in places ; brittle 

 and hard when dry ; taste and odor slight ; no odor of fenugreek. 



Spines sharp, slender and crowded, about 3-5 mm. long, short and 

 fading away towards the sterile margin, at first pallid and then a deep 

 brown color; somewhat decurrent. 



Stem usually slender and short, up to 3 cm., mostly about 2 cm., 

 long; surface about color of cap, covered with a thin la^'er of soft 

 spongy tissue which surrounds and binds adjoining particles ; center 

 hard and tough. 



Spores roughly globose, unevenly tuberculate, about 4-4.8 x 5m in 

 diameter. 



This species is most like H. zonatum, from which it is distinguished 

 by the thicker and more rigid substance, by the nonzonate and 

 much rougher cap, the center usually with sharp pits and prolifera- 

 tions like scoria. Our plants look just like Fries' figs. (Plate 5) and 

 like several collections under this name at the Xew York Botanical 

 Garden.
