lections are not listed here or later because of the uncertainty of 

 the locality. The number of exsiccati in the various herbaria 

 indicate that this species is common throughout the eastern states.

Fries' description. H. lacunosa, pileo inflato lobato cinereo- 

 nigro, lobis deflexis adnatis, stipite fistuloso costato-lacunoso. 

 Ab antecedente (H. crispa), pro cujus varietate facile sumi 

 posset, differet pileo magis regulari, 2-4-lobo, vix laciniato, lobis 

 serius liberatis & praecipue colore. Statura plerumqu.e minor, 

 subinde tamen aeque procera occur rit s. Helvella mitra g. pra- 

 tensis Alb. & Schwein. consp. p. 298. Quamvis igitur charac- 

 teres acuti desint, in natura constans ; etiam in cibariis vilior. 



H. sulcata, pileo deflexo lobato adnato, stipite farcto costis 

 aequalibus sulcat. Solitaria, raro gregaria, tota glabra, certe a 

 priori diversa. Stipes farctus, 2 unc. longus, 4-5 lin. crassus, 

 teres, sursum attenuatus, sulcis longitudinalibus profundis ex- 

 artus, costis tenuibus solodis, nec lacunoso-fistulosis ut in prae- 

 cedentibus. Pileus deflexus aequaliter 2-3-lobus, compressus, 

 laevis, exsiccatus obscurior, latere interiori stipiti adnatus. 



Pileus lobed, saddle-shaped, compressed or irregular, lobes de- 

 flexed and adnate with the stipe, firm, varying in color from 

 smoke-gray to almost black, 1.5-5 cm - broad, glabrous, smooth, 

 or lower surface rugulose. Stipe even or attenuate upward, or 

 downward, sometimes ventricose, smoke-gray, sulcate-costate, 

 with the costae sometimes anastomosing by their outer margins, 

 sometimes free throughout the extent of the stipe, costae solid 

 in our specimens but said to be sometimes hollow, stipe formed 

 as in H. crispa, 1.5-10 cm. in height by 0.5-2 cm. in diameter. 

 Asci cylindrical, 250-350 X 15-20/x. Spores ellipsoidal, hyaline, 

 smooth, with large central oil drop and some very much smaller 

 ones, 15-19 X 10-12/A. Paraphyses slender, septate, enlarging 

 upward, hyaline or brown tinted. (PL 11, figs. 2, 3, 4, 5.)
