 inrolled until maturity, then expanded or uplifted so as to become 

 infundibuliform, surface viscid, sparingly and rather coarsely tomen-

 towards maturity. Zoned with soaked ochraceous and lighter honey- 

 colored tints. Flesh 6 mm. thick at stem, thinning regularly to

 branched, a clear ochraceous buff at maturity, turning smoky-brown 

 when bruised. 



Stem 1.5-3 cm. long, 9-12 mm. thick at stem, tapering strongly 

 downward, 4-5 mm. at base, surface pure white or stained with buff,
