IOWA DISCOMYCETES 79 



exuding a milky, colored juice ; asci cylindrical, 8-spored ; spores 

 elliptical hyaline. 



One species common in Iowa. 



Galactinia succosa (Berk.) Sacc, Syll. Fung., 8 : 106. 1889. 



Plate 16, f. ii. 



Peziza succosa Berk., Not. Brit. Fungi. No. 156 (reprint from 

 Ann. Mag. Nat. Hist. 1841). 



The plants of this species are not striking in external appear- 

 ance but are easily distinguished by the bright yellow, milky 

 juice which exudes when the flesh is broken. There seems to be 

 two varieties of this species distinguished mainly by the differ- 

 ence in size. The one is small, scarcely reaching a size of 2 cm. 

 in diameter and the cups very regular and almost perfectly 

 hemispherical in form. The other is much larger often reaching 

 a size of 4 to 5 cm. and the cups are not perfectly hemispherical 

 but the sides are more nearly straight giving the plant more or 

 less of a funnel-shaped appearance. Whether the two forms are 

 entirely distinct is uncertain. 



OTIDEA (Pers.) Fuckel, Symb. Myc, 329. 1869. 



Otidea (subgenus) Pers., Myc. Eu. 1 : 220. 1822. 



Receptacle large, elongated or split on one side nearly to the 

 base ; cups more or less stipitate, scattered or densely crowded ; 

 asci cylindrical, 8-spored; spores elliptical, smooth, hyaline with 

 one or two oil-drops; paraphyses clavate or bent in the form of 

 a hook at the apex. 



KEY TO THE SPECIES. 



Plants large, hymenium brown, paraphyses, hooked. . . 0. leporina. 

 Plants comparatively small, yellowish, paraphyses 



straight °- ocliracea. 



*Otidea leporina (Batsch) Fuckel, Symb. Myc, 379. 1869. 



Peziza leporina Batsch, Elench. Fung., 1 : 118. 1783. 



The large cups much elongated on one side are very good 

 characters by which the present species may be distinguished.
