Anderson & Ickis: Massachusetts Species of Helvella 227 



condition of the ascoma and its more permanent cup-shape place 

 it among the Pezizales rather than among the Helvellales. Phil- 

 lips (1893) finds however that the cups sometimes become ex- 

 panded or even reflexed. In this condition it would be more 

 easily taken for a Helvella. The above description is taken 

 largely from Rehm. Massee describes the plants as somewhat 

 larger, 2-5 cm. broad and 3-7 cm. high ; also he finds the spores 

 28-33 X 11-13/x. Boudier (Icon. Myc. 4: 126) finds that it 

 sometimes grows 10 cm. high, never reflexed, the spores having 

 usually 3 oil drops, 24-29 X 11-12^, fusiform. Among the 

 Massachusetts Helvellae it is most closely related to H. ephip- 

 pium, from which species it is probably most easily separated by 

 its larger ellipsoid-fusiform spores. 



Peck (Bui. Tor. Club 29: 74. 1902) described Helvella ma- 

 cropus v. brevis from some small specimens which were sent to 

 him from this state by Morris. Stipe 8-16 mm. long and pileus 

 8-16 mm. broad, hymenial surface black or nearly so. These 

 differences seem hardly sufficient basis for the separation of a 

 variety. The writers studied the type specimens at Albany as 

 well as another collection sent to Peck by Simon Davis from 

 Mass. The specimens were very similar to our exsiccati of H. 

 ephippium, but the spores are distinctly fusiform, minutely tu- 

 berculate and measure 18-25 X 10-12/x, corresponding in every 

 respect with those of Macropodia macropus.
