210 Banker: A preliminary Contribution 



H. scrobiculatum. The Ohio specimens have not 



been seen. Morgan's Kentucky specimens answer well to the de- 

 scriptions of H. infundibulnni except as to size. The European 

 plant is described as 20 cm. wide and with stem 5—8 cm. long and 

 3 cm. thick. Morgan's specimens are 4-7 cm. wide with stem 4-5 

 cm. long, a much smaller plant. The plant is distinguished by its 

 infundibuliform pileus, with erect flexuose, plicate margin.

Reported from Rhode Island (Bennett); Pennsylvania (Schwei- 

 nitz) ; South Carolina (Schweinitz, Curtis, Ravenel). Bennett's 

 Rhode Island specimen is unquestionably H. scrobiculatum and 

 therefore must be excluded. Schweinitz's specimen is doubtful, 

 the others have not been seen. Schweinitz's Pennsylvania speci- 

 men is identical with a specimen in the Underwood herbarium re- 

 ferred to H. imbricatum and characterized by coarse aculei, a slen- 

 der stem and a remarkably light porous substance to the pileus

when dried. This species so far as our American forms are con- 

 cerned is doubtless involved in confusion with H. imbricatum. A 

 thorough investigation is greatly needed of these related species 

 including H. levigatum.

* In one set of N. A. F. under this number there was found a most typical specimen 

 of what I regard as H. imbricatum, in another set under the same number the speci- 

 men appears to be a very distinct thing and entitled to be treated as a different species.
