98 The North American Cup-Fungi 



larger cup-fungi, occurring from the Atlantic to the Pacific and 

 probably throughout temperate North America as well as abroad. 

 Also it is attractive and easily recognized by means of its bright- 

 orange color. If there is any doubt of its identity, this can be 

 easily dispelled by an examination of the beautifully reticulated 

 spores. 



2. Aleuria wisconsinensis Rehm, Ann. Myc. 2: 34. 1904. 



Apothecia gregarious, sessile, becoming discoid, contracted at 

 the base into a slightly stem-like base, the margin thick and 

 entire, at length becoming more or less convolute, externally 

 light-colored, yellowish, tomentose, reaching a diameter of 0.5- 

 2 cm.; hymenium slightly concave or plane, even or convolute, 

 bright orange-red; the excipular cell walls subhyaline; asci 

 cylindric or subcylindric, reaching a length of 200 yu and a 

 diameter of 10 /x, 8-spored; spores 1-seriate, ellipsoid, hyaline, 

 containing two large oil-drops, becoming sculptured, about 

 7 X 14-15 m; spore-sculpturing taking the form of reticulations; 

 paraphyses hyaline, filiform, septate, reaching a diameter of 5 /x 

 at their apices and about 3 jjl below. 



On damp soil. 



Type locality: Blue mounds, Wisconsin. 



Distribution: Wisconsin and Minnesota.

 Aleurina Lloydiana Rehm, Ann. Myc. 2: 35. 1904. 

 Peziza Commonsii Ellis & Ev. (in herb.). 



Apothecia gregarious or densely crowded, sessile or sub- 

 sessile, and circular or becoming irregular from mutual pressure, 

 reaching a diameter of 5-6 mm. or rarely 1 cm., externally 

 yellowish-orange ; hymenium shallow-concave or becoming nearly 

 plane, orange; asci cylindric or clavate, reaching a length of 

 150 jx and a diameter of 10 n, 8-spored; spores 1-seriate, ellipsoid, 

 at first smooth and containing two distinct oil-drops, 5-7 X 10- 

 11 M, becoming sculptured; spore-sculpturing taking the form of 

 very fine reticulations, with one or two projections at either end 

 and giving the spore an apiculate appearance (the mature spores 

 resembling those of Aleuria aurantia except that they are much 

 smaller), hyaline or subhyaline; paraphyses slender, rather
