98 MINNESOTA BOTANICAL STUDIES. 



On trunk and branches of Abies balsamca; Cass, Sept. 1896, A. 

 P. Anderson. 



The above description is taken from A. P. Anderson's paper in 

 Bull. Torr. Hot. CI. 29:23-34, 1902. The specimens were not de- 

 posited in the University herbarium and tlie writer has therefore 

 not had an oi)])ortunity to examine them.

3. DASYSCYPHA FUCKEL. 



Cups gregarious, fleshy-waxy, minute, stipitate, concave to ])lane ; 

 exterior pilose or villose, hairs short, white or gray; spores ellipti- 

 cal or fusiform, smooth, hyaline, generally two-celled. 



1. Dasyscypha agassizii (B. & C.) Sacc. Syll. Fung. 8:438. 1889. 

 Peziza {Humaria) Agassicii B. & C. North American Fungi, 



no. 713. Grev. 3: 151. 1875. 



Gregarious or single, stipitate, 1-2 mm. high and to 4 mm. wide; 

 flattened when moist, concave when dry ; hymenium smooth, lemon 

 yellow to orange-yellow ; margin undulate, incurved ; exterior and 

 sliort stipe white tomentose, hairs short ; spores elliptical to sub- 

 fusiform, smooth, hyaline, mainly continuous with small guttulae, 

 some show tendency to be uniseptate, 4-7.5 x 2-4 mic. ; paraphyses 

 slender, granulate, very slightly clavate, free at tip. 



On balsam trunks and dead sticks ; St. Louis, July 1886, Holway 

 179; Cook, Aug. 1903, Freeman & Ballard 70, 141. 



This was first thought to be D. rcsinaria and to agree with col- 

 lections made by A. P. Anderson at Walker, Minn., described in 

 Bull. Torr. Bot. CI. 29: 1902, but upon farther examination both 

 the spores and ascophore prove to be too large.
