Plant terrestrial, mesopodous, medium size ; pileus obconic, 

 deeply depressed -to infundibuliform, somewhat round, 

 thickest at the center, thinning uniformly to the margin, 

 4 to 6 cm. wide, i cm. or less thick near the center; surface 

 subeven, radiately subrugose or fibrillose when fresh, gray- 

 ish umber; margin thin, acute, coarsely plicate or fluted, de- 

 flexed, curled when dried, subfertile with short teeth; sub- 

 stance spongy-tomentose in upper half of pileus, thickest at 

 the center, umber, lower part of pileus harder more compact 

 darker of uniform thickness about I mm., continuous with 

 hard central core of stem ; stem central, uneven, surrounded 

 below by bulbous mass of spongy tomentum, 0.5 cm. wide, 

 4 cm. long, bulbous base 1.5 cm. wide; teeth capillary more 

 or less decurrent, dark umber to black, 7 mm. or less long, 

 0.15 to 0.25 mm. wide, about 2 to I millimeter, longest teeth 

 about one-fourth of the distance from the stem to the mar- 

 gin; spores apparently few, subtuberculate, subglobose, 

 brownish, 4 to 5 /* wide. 



The plant in structure is similar to H. velutinum, but very 

 distinct in the form of the pileus, in its subrugose not to- 

 mentose surface, and in the long capillary teeth.
