Mycologia 



saddle-shaped or irregularly 2-3-lobed, usually tilted — so much so 

 in some cases that it is almost vertical and the reflexed lobes en- 

 circle the stipe — margin even or wavy and free from the stipe, 

 upper surface light-drab, smoke-gray or yellow but often found 

 darker, through various shades of gray-brown or fuliginous, 

 1-3.5 cm. broad, lower surface white, pruinose to tomentose, 

 usually areolate. Stipe slender, smooth and terete or frequently 

 somewhat uneven and undulating, compressed at places or lacu- 

 nose but never sulcate-costate, attenuate upward, pruinose to to- 

 mentose, 3-10 cm. high by 4-8 mm. diam. at the base, pure-white, 

 sometimes darker toward the base and exhibiting there the same 

 colors as the pileus, stuffed or finally hollow. Asci 200-300 X 

 12-18/A. Spores ellipsoidal, smooth, hyaline, 17-20 X 1 0—12/*, 

 with large central oil drop. Paraphyses slender, septate, clavate, 

 hyaline. (PI. 12, figs. 8-15.) 



On the ground and sometimes on wet rotten logs in the woods. 

 Common in autumn. 



The shape of the pileus is extremely variable. It only rarely 

 appears to be set squarely on the top of the stipe but in our 

 specimens has almost always been tilted at various angles as in- 

 dicated by our photographs. If tilted to nearly the vertical posi- 

 tion, the reflexed margins roll closely about the top of the stipe. 

 Sometimes longitudinal lacunae on opposite sides extend clear 

 through the stipe, the fissure thus formed making the stipe appear 

 double for a part of its length (fig. 8). The stipe is always 

 slender ; we have never found one that was as much as 1 cm. in 

 diameter; it is difficult for us to believe that they become 1 inch 

 thick in Minn, as described by Miss Hone. H. albella Quel. (= 

 Leptopodia albella of Boudier) is separated on the basis of a 

 darker colored pileus. In view of the well-known variations in 

 the shade of the pileus such a character would hardly seem suffi- 

 cient for separating a species. In his supplement to Vol. II of 

 the Systema Mycologicum, Fries states that he has seen many 

 varieties of colors, snow-white, brown, etc. 



Peck describes his new species H. gracilis as having the upper 

 surface of the pileus pale-yellow, but in all other respects his 

 description agrees with that of H. elastica. Cook (Mycogr. 

 1 (I): 91 and fig*. 162) after examining the specimens of H. 

 gracilis which Peck sent to him says : Size and habit that of H. 

 elastica, wholly ochraceous. Sporidia 18-20 X I2ft. It is appar-
