Otidea leporina Saccardo. Sylloge Fung., VIII, p. 94. 

 L897 Otidea leporina Engler-Prantl, Pflan. Famel. , I, p. 187. 



Cups substipitate, elongated on one side, split on the short 

 side near the base, cleft margin ir curved, margin inclined to 

 be scalloped, 1 to 3 inches in diameter; hymenium dark brown, 

 externally lighter; asci cylindrical; sporidia 8, elliptic, smooth, 

 2-guttulate, 12 to 14 by 7 to 8 microns; paraphyses filiform, 

 curved at their apices. 



Habitat — On the ground in the woods; collected by B. 

 Shimek in Winneshiek County, Iowa. 



Plants distinguished from those of Otidea ochracea Fr. ex- 

 ternally by their larger size and darker color. Upon micro- 

 scopic examination they are distinguished by their paraphyses 

 which are always curved in the form of a hook at the apex. 

 These characters also distinguish this species from Otidea 

 onotica which is similar to Otidea ochracea Fr. but much 

 larger in size and more stipitate in form.

 Otidea ochracea Saccardo, Sulloge Fung., VIII, p. 95. 



Cups small, 2 to 3 cm. in diameter, caespitose or solitary, 

 continued into a short thick stem-like base below, base cor- 

 rugated; cups split on one side to the base and margin in- 

 curved; asci cylindrical, 8-spored, no to 130 by 10 microns; 

 paraphyses not enlarged at their apices, septate, granular, 

 branched often several times. 



Habitat — On soil among leaves in woods, Winneshiek 

 County, Iowa. Collected by B. Shimek. 



This form is distinguished from Otidea onotica (Pers.) Fckl. 

 by its smaller size and yellowish color. The spore measure- 

 ments also seem to be somewhat less. The cups are not much 

 elongated on side, if any, but are split to the base. Plants 

 distinguished from O. leporina (liatsch) Fckl. by their smaller 

 size size, yellow collor, and straight paraphyses.
