Anderson & Ickis: Massachusetts Species of Helvella 219 



by Leveille as round but we find them much the same as in other 

 species of the genus except perhaps that they are a little smaller 

 (14-16/x long in our specimens). 



In this species we have a connecting link between the Hel- 

 vellae and the Pezizales. One who sees only the younger cupu- 

 lar ascomata is inclined to place it among the latter but in more 

 mature stages the helvelloid character appears. 



Massachusetts Collections. Sunderland, Sept., 191 9 (Ander- 

 son & G. W. Martin) M. A. C. Herb. 2644; Leverett, Oct., 1920 

 (Ickis). There are specimens under this name in the Harvard 

 herbarium, collected by Mrs. Sanger at Manchester, Mass., in 

 Aug. 1906, but they could hardly be H. ephippium as we know 

 it, since they are much larger, have lacunose stipes, and the 

 margins of the pilei are adnate. 



In Peck's herbarium there are two packets of this species from 

 Mass., one from G. E. Morris, of Waltham, and the other from 

 Miss Hallowell, but no localities or dates are given.
