Solitary, sessile, waxy, Heshy, hemispherical becoming cup-shaped 

 or cochleate, margin incurved at first becoming erect, generally en- 

 tire ; hymenium up to 2 cm. in diameter, mouse-colored, even, ex-

 described for P. succosa Berk, in a fresh state.

2. Galactinia sarazini Bcud. Bull. Soc. Myc. France. 3: 147. 1887. 

 Caespitose, sessile, plicate and folded at the base, some contorted 



ethers hemispherical becoming expanded to cup-like and occasion- 

 ally repand. up to 2.5 inches across, to 1.75 inches high; hymenium 

 brown, very much folded, dark ; exterior pruinose to farinose al- 

 most white to gray at plicate base growing dark upwards until 

 margin is as dark as the hymenium ; margin entire, wavy, often 

 crenate ; spores elliptical, obtuse, hyaline, verrucose, some having 

 a short, broad papilla at each end, biguttulate. 10-12x4-6 mic; 

 paraphyses slender, clavate, apex colorless, granulate. 4-6 mic. wide. 



On burned-over ground ; Hennepin, July 1900, Hibbard. 



Near allies of the Minnesota specimens are Peziaa zvarnei Peck 

 (146, p. 59), which disagrees in habit and shape of the papillae at 

 the end of the spores; Discina leucoxantha Bresadola (35, p. 42), 

 which disagrees in greater size of the spores and color of the fungus.' 

 The n-aterial described is wholly brown and gray to white with no 

 yellow shades. Pe:::iza cchinospora Karst. (113. p. 54-) Cooke 48, 

 p. 247) and Pcziza emileia Cooke (48, f. 379). are also near 

 relatives dififering in color and larger spores. Roumeguere, Fungi 

 Gallici, 3453 (P. emileia Cke.), shows spores of exactly the same
