11. H. olivaceo-albus Fr. Pileus 2.5-5 cent - ( : ~ 2 in O broad, 

 olivaceous-fuscous, becoming pale, especially towards the margin, 

 which is at the first naked, fleshy, at first acorn-shaped, then 

 expanded, umbonate, and at length depressed round the umbo, 

 wholly even, smooth, glutinous; flesh thin, white. Stem about 

 7.5 cent. (3 in.) long, 6 mm. (3 lin.) thick, solid, equal or attenuated 

 at the very \>2JS>e,squaimdose and spotted with the fuscous veil, which 

 is in the form of an adnate sheath, viscid, but the ground colour 

 is white ; veil terminating near the apex in the form of a ring 

 above which the stem is even, shining white. Gills decurrent, 

 distant, broad, simple, connected by veins at the base, always 

 shining white. 



Margin somewhat striate when old. Scattered throughout the summer in 

 rainy weather, not enduring cold, and hence very different in its nature from 

 H. hypothejus, which is allied.
