Mycologia 



under H. sulcata, he has form fusca with black pileus, brown 

 stipe becoming ash-gray on drying and form cinerea which is 

 entirely ash-gray. Boudier describes H. lacunosa as having the 

 pileus black both above and below and the stipe somewhat lighter, 

 while in H. sulcata it is blackish or cinereous with a paler stipe. 

 Willdenow mentions a variety of H. sulcata which is entirely 

 white. One concludes after reading the descriptions of the 

 various authors that the shade of color is extremely variable but 

 it is agreed by all that it can be readily distinguished from H. 

 crispa by its sombre hues. Also in this species we do not find 

 the margin curled upward as in H. crispa, and in our collections 

 the pileus has never been found entirely free from the costae. 



Massachusetts Collections: Sprague (1856), Frost (1875), and 

 Underwood (1896) have included this species in their lists of 

 New England fungi but the localities from which they were col- 

 lected are uncertain. Waltham, Aug. 1898 (Morris), Bost. Myc. 

 Herb.; Wareham, Sept. 1912 (E. C. Ellis) Bost. Myc. Herb.; 

 Holbrook, Aug. 1899. (Alice L. Grinnell) Bost. Myc. Herb.;

 E. Morris) N. Y. Bot. Gard. Herb.; Boston, July 1909 (Mor-

 It appears to be a common species in this state.

Peck's original description. Pileus irregular, at first blackish 

 and slightly adnate, then grayish brown or mouse-colored and 

 free, rugose beneath; stem equal, slender, sulcate-costate, col- 

 ored like the pileus, the costae thin, subacute; asci cylindrical; 

 spores' broadly elliptical, .00064 i n - to .0008 in. long, .0005 in. 

 broad, containing a single large nucleus ; paraphyses thickened 

 above, brown.

This species is related to H. sulcata, from which it differs in 

 its more slender and darker colored stem, its less firm and more
