92 THE AGARICACEAE OF MICHIGAN 



cate or centrally depressed, occasionally subinfundibuliform, cov- 

 ered with long matted hairs or tomentum, the center sometimes 

 naked with age, azonate, viscid when moist, white, reddish, buff or 

 dingy incarnate. FLESH soft. GILLS adnate or slightly decur- 

 rent, thin, rather narrow, close, some forked, white or tinged with 

 yellow or incarnate. STEM 2-3 cm. long, 6-12 mm. thick, short, 

 equal or tapering downward, pruinose, stuffed then hollow, not 

 spotted, white or whitish. SPORES globose-elliptical, 6-8 micr., 

 white. MILK white, sparse, slowly changing to pale yellow, acrid. 



"In pine woods. September-October." 



The description is adapted from Peck (N. Y. Mus. Rep. 38) who 

 remarks that it is distinguished from all others by its conspicuously 

 woolly pileus. The hairs or fibrils are long and intricately matted, 

 and very viscid in wet weather. The milk is said to be very sparse, 

 and in a white variety, sometimes wanting. I have not yet found it 

 in the state, but as it is said to be poisonous like the preceding, to 

 which it is closely related, it seemed desirable to include it. The 

 white variety might be mistaken for a Russula.
