I08 MINNESOTA BOTANICAL STUDIES. 



I. TAPESIA FUCKEL. 



Cups gregarious or solitary, waxy, sessile, concave then plane, 

 minute; exterior glabrous but scaly; spores elliptical-fusiform, 

 smooth, hyaline, continuous ; myceliuiii superficial, more or less 

 tomentose white, yellow or dark brown. 



I. Tapesia fusca (Pers.) Fckl. Sjrmb. Myc. 302. 1869. 



Pccica fusca Pers. Observ. Alyc. i : 29. 1796. 



Gregarious or scattered, sessile upon a subiculum of densely 

 spongy^ dark brown, interwoven hyphae, 4-5 mic. wide, hyphae 

 sometimes scanty or almost obsolete ; cup convex when young be- 

 coming plane with raised margin ; margin often irregular, papillose 

 with faint resemblance to hairs ; hymenium dirty watery-white to 

 yellowish, i mm. in diameter; exterior brown, glabrous; spores el- 

 liptical-fusiform, hyaline, smooth, simple, generally eguttulate, 

 mainly continuous, some appear pseudoseptate, 6-9 x 2-3 mic. ; 

 paraphyses slender, clavate. 



On rotten log; Wright, May 1900, Freeman 642. 



Specimens may not be fully mature and thus the spores are small 

 for Tapesia fusca (Pers.) Fckl.; nevertheless they agree in color, 

 marginal characters, and size.
