Hone: pezizales, phacidiales and tuberales of minn. 8i 



thread-like, branched, numerous, not clavate, up to 4 mic. wide. 



On decayed wood on ground ; Cook, Aug. 1903, Freeman & Bal- 

 lard 135.

 Peziza microspora Berk, and Curt. Grev. 3: 150. 1875. 

 Gregarious and caespitose, sessile or substipitate, fleshy, fragile, 



very irregular, up to 2.5 cm. across ; hymenium smooth, bright 

 orange ; exterior pallid, pruinose ; stipe obsolete or very short, a 

 mere fibril sometimes; spores elliptical, obtuse, smooth, 1-2 gut- 

 tulate, 6-8 x 3-4 mic. ; paraphyses slender. 



On rotten wood near ground and on the ground ; Hennepin, 

 Sept. 1900, Freeman 787. 



The original description for Pezisa microspora B. & C. in Grev. 

 3: 150 omits any reference to size and the Minnesota specimens are 

 larger than those previously described ; e. g. Cooke's measurements 

 give only .25 inch. Peziza epispatica B. & Br. is very near and agrees 

 in size, but both color and tomentose-pulverulent character disagree. 



4. Humaria fuscocarpa (Ellis & Holway) Morgan, Journal. Myc. 8: 



189. 1902. 



Peziza fuscocarpa (Ellis & Holway) Morgan, Journal. Myc. 8: 

 189. 1902. 



Aleurina fuscocarpa Sacc. Syll. Fung. 16:739. 1902. 



Scattered or gregarious, sessile, orbicular, 3-4 mm. in diameter ; 

 margin incurved ; hymenium concave, olive-black ; exterior pruinose, 

 lighter colored ; spores elliptical, obtuse or acute, biguttulate, con- 

 tinuous, smooth, yellow-brown, 8-10x4 mic; paraphyses filiform. 



On old rotten logs; St. Louis, July 1886, Holway 194; Dakota, 

 July 1893, Sheldon 5396. 



Rehm (178, p. 514.) calls attention to the smooth character of 

 Pedza fuscocarpa E. & H., with which the Minnesota material 

 agrees. This species is retained under Pesiza as originally placed, 

 although Lindau makes no special provision for brown, elliptical- 

 spored forms.
