lae and at the same time agrees with our Gyromitrae in its vernal 

 habit. Its size, color and stout stipe also indicate a relationship 

 to Gyromitra. The spores as described by Rehm are like those of 

 Helvetia rather than Gyromitra. In the few herbarium specimens 

 which we have found and examined microscopically the spores 

 were biguttulate and we are inclined to believe that the specimens 

 were incorrectly referred to this species. We have included a 

 consideration of this species in this paper, even though based on 

 very scanty data in the hope that mycologists might be induced to 

 look more carefully for it and settle the question as to its iden- 

 tity. * 4 / 



Massachusetts Collections: Sprague (1858) included this 

 species in his second list of New England fungi and indicates by 

 the context that it was collected in the vicinity of Boston. Morris 

 (1918) has doubtfully attached this name to a drawing of a 

 species which he collected at Ellis in Sept. 191 3. If it was H. 

 Monachella, it differed from the European plant in its autumnal 

 occurrence.

Pileus at first globose and closed, then opening to expose the 

 grayish-brown hymenial surface, which is at first cup-shaped, 

 then saucer-shaped, 1-3 cm. broad, smooth above, coriaceous, 

 fragile. Stipe cylindrical, 1-4 cm. high, 1-3 mm. in diameter, hol- 

 low, attenuate upward, frequently somewhat lacunose. The stipe 

 and lower surface of the pileus are gray, scurfy-villose, with tufts 

 of closely septate moniliform clavate hairs, 10-12^ thick at their 

 apices. Asci cylindrical, 300-350/x X 14-16/x. Spores ellipsoid- 

 fusiform, hyaline, smooth or sometimes rough, mostly with a 

 large central oil drop, 18-^25 X 10-^12/a. Paraphyses slender, 

 septate, enlarging upward to 8/x, yellowish. 



This is not a true Helvetia but is included in this paper be- 

 cause frequently called a Helvetia (following Karsten), and be- 

 cause it is commonly found in Massachusetts. The early closed
