lately convex then expanded and depressed, fragile when 

 adult, with a viscid pellicle, losing its colour, margin at. 

 length sulcate and somewhat tuberculose; flesh white, 

 sometimes yellowish upwards. Gills almost free, very 

 broad, equal or bifid near the base, rather distant, con- 

 nected by veins, pallid white then yellow; pulverulent with 

 the somewhat ochraceous spores, a character by which the 

 jiresent species is readily known. Gills sometimes quite- 

 sterile, and hence remaining persistently white. (Fries.)
