thing, while Schaeffer's plant is readily recognized from his figure 

 and is clearly characterized by the white or cream colored teeth, 

 the darker zonate pileus, somewhat tomentose at the center, and 

 with margin the color of the teeth. The pilei are frequently con- 

 fluent, forming a thin expanded crust supported by the slender dis- 





tinct stems.

Type Loc. : Bethlehem, Pa. (Schweinitz). 



This species has not been reported except by its discoverer. 

 The type specimen in the Schweinitz collection at Philadelphia is 

 partly destroyed, but sufficient remains to show the chief charac- 

 ters of the plant. It is a very dainty little species, 1.5-2 cm. 

 high, ash-gray in color ; pileus thin, flat to infundibuliform ; stem 

 attenuate to the base. A plant in the Ellis collection at the N. Y. 

 Botanical Garden marked H. suffocatum is to all appearances this 

 species and so gives another station, Newfield, N. J.

Type Loc. : North Carolina (Schweinitz). 



Also reported from Bethlehem, Pa. (Schweinitz). 



The species has never been reported by any other than 

 Schweinitz himself. His description is too brief to convey any 

 definite idea of the species. Fries regarded the plant the same 



*acile with a confidence that would indicate he had seen 

 something more than Schweinitz^ three-line description. The 

 specimen in the Schweinitz collection at Philadelphia, while not 

 very satisfactory, appears to be a plant closely resembling H. 

 scrobiculatum in all important features except that the color is ash- 

 gray.
