Plate 40. Figure 16. X 1 



Pileus tough, conchate, spatulate to reniform, about 1-3 cm. 

 broad; surface isabelline to subfulvous, nearly even, zoned at 

 times, the cuticle breaking into granules or small scales, margin 

 entire or lobed, incurved when young ; context thin, firm, rather 

 tough, watery-white, taste not always evident at once, but becom- 

 ing strongly acrid and astringent ; lamellae narrow, thin, crowded, 

 interveined, isabelline, determinate ; spores globose, smooth, hya- 

 line, 2-4 X 1-3 p ; stipe lateral, short, swollen above, solid, com- 

 pressed, pruinose, pale-isabelline or dull-white above, darker 

 below. 



This small, inconspicuous species is common throughout tem- 

 perate regions during autumn and winter on stumps of deciduous 

 trees in woods. It is phosphorescent, and also poisonous, possess- 

 ing a strongly acrid and astringent taste, but it would hardly be 

 collected for food even if well-flavored because of its small size 

 and apparent toughness.
