Anderson & Ickis : Massachusetts Species of Helvella 215 



free pileus and its darker colored paraphyses. In the dried speci- 

 mens the upper surface of the pileus has assumed a blackish 

 color, but the lower surface has retained very nearly its normal 

 hue. The dark colored slender stem readily separates this species 

 from all others with costate or lacunose-costate stems. 



We have found but a single specimen of this species. The 

 entire plant was gray, the slender stipe 5 cm. high by 3 mm. thick 

 and beautifully fluted with prominent veins which did not anas- 

 tomose. The pileus was entirely free, not firm, almost smooth 

 beneath. Spores measured 14-18 X J-iOix and could not be dis- 

 tinguished from those of other Helvellae. In order to clear up 

 doubts about this species we studied carefully the specimens in 

 Peck's herbarium at Albany. Six specimens were found but they 

 were in imperfect condition. The place of collection was Manlius 

 Center but no date was given (a frequent omission in the Peck 

 herbarium) and it was of course impossible to say whether it 

 was the type material. In the dried state the pilei were about 

 2 cm. in diam. and black, the stipe 4 cm. high X 3 mm. diam., 

 sulcate costate, bistre or a little lighter upward, pileus attached 

 in some but mostly free, finely wrinkled below. Whether or not 

 the differences are sufficient to warrant the separation of this 

 form from H. lacunosa as a distinct species is a question which 

 can be answered only by study of more abundant fresh material. 

 It is also very similar to H. Queletiana. In the absence of more 

 abundant material for investigation we have considered it as a 

 distinct species.
