when dry, slightly squamulose with superficial subfasciculate whitish 

 fibrils, the margin sometimes appearing slightly and fugaciously 

 appendiculate with these fibrils ; lamellae broad, subdistant, adnate, 

 grayish or cinereous, becoming brown or blackish brown, white on 

 the edge ; stem slender, hollow, fragile, floccosely pruinose, white ; 

 spores brown, 8 x 5 ju,. 



Pileus 1 .2-2 cm broad ; stem 7,-7 cm long, 2 mm thick. 



Decaying wood in woods. Ulster co. September. Rare. 



The superficial fibrillose and evanescent squamules of the pileus 

 are similar to those on the pileus of P s i 1 o c y b e canofaciens 

 Cke. but the white stem of our plant at once distinguishes it from 

 that species. The specific name has reference to the white fibrils 

 of the pileus which suggest the white hairs of old age.
