Pileus convex or subcampanulate to subumbonate, densely cespi- 

 tose, 3-5 cm. broad ; surface dry, white or grayish, darker and 

 sometimes rugulose on the disk, ornamented with a f ew appressed, 

 pale-umbrinous or avellaneous, floccose-fibrillose scales; context 

 white, soft, watery, thick, thin at the margin, odorless, mild ; lamel- 

 lae adnate or sinuate, rather crowded, whitish, becoming dark- 

 brown, whitish and sometimes weeping on the edges ; spores ob- 

 long-ellipsoid, smooth, brown, 6-8 x 3-4 jx\ stipe long, slender, 

 equal, fibrillose, striate at the apex, white to discolored, often yel- 

 lowish at the base when bruised, solid or hollow, 5-10 cm. long, 

 4-10 mm. thick; veil white, thick, often forming a fragmentary 

 annulus. 



Type locality : Sweden. 



Habitat : In rich soil in woods, usually about logs or stumps. 

 It seems fond of beech. 



Distribution : New York, New Jersey, Michigan, and probably 

 in other parts of the eastern United States ; also in Europe.

This species was first named by Fries from specimens collected 

 by himself about beech trees in Sweden, the covering of matted 

 hairs suggesting to him the specific name used. He saw it only 

 twice, and it is rare in America, although several times collected 

 about New York City. The plants first seen by Peck from Alcove 

 were considerably smaller than the European form, but his variety 

 sericeum, from North Bolton, is larger and smoother. Those 

 interested in the rather complicated history of the species may refer 

 to Maire's notes in Bull. Soc. Myc. France 27: 441-445. 1911,
