218 The North American Cup-Fungi 



Distribution: (Nebraska?) and (Bermuda?); also in Europe. 



Illustration : Cooke, Mycographia pi. 79, f. 305. 



A small specimen collected in Bermuda by B. O. Dodge seems 

 to belong here so far as spore characters are concerned. How- 

 ever, the material was so limited that it was impossible to make 

 a careful study of the gross characters. Also Peziza elaeodes of 

 Clements seems to fit Cooke's description but here again it was 

 impossible to be certain for lack of material. So the species 

 must remain doubtful so far as its record from North America 

 is concerned. 



3. Discina convoluta Seaver, Mycologia 13: 70. 1921. (Plate 

 28, fig. 1.) 



Apothecia gregarious or cespitose, very short-stipitate, be- 

 coming shallow cup-shaped or subdiscoid, externally whitish at 

 the base, becoming yellowish upwards toward the margin, 

 reaching a diameter of 6 cm.; hymenium yellowish-brown, very 

 deeply convolute, the convolutions consisting of more or less 

 radiating ribs or veins, resembling those of Peziza venosa but 

 more distinct; stem very short and stout, 1 cm. or more thick 

 and usually not more than 1 cm. long, whitish, deeply corrugated ; 

 asci cylindric or subcylindric, reaching a length of 400-500 n 

 and a diameter of 20 ix, 8-spored but a part of the spores often 

 remaining undeveloped; spores 1-seriate, with the ends usually 

 overlapping, ellipsoid, becoming sculptured and appendiculate 

 12-14 X v35-40/x; spore-sculpturing consisting of warts or short 

 interrupted ridges which often approach very fine reticulations; 

 spore appendages consisting of a cup-like structure at each end; 

 paraphyses stout, usually straight, reaching a diameter of 8 /i at 

 their apices, densely filled with yellow granules. 



On the ground in woods. 



Type collected in the woods near Yonkers, New York, May 

 22, 1916, by F. J. Seaver. 



Distribution : Known only from the type locality. 



4. Discina leucoxantha Bres. Rev. Myc. 4:212. 1882. 



Peziza leucoxantha Bres. Fungi Trid. 1: 42. 1883. 



Apothecia gregarious or substipitate, at first subglobose, 

 expanding and becoming hemispheric or nearly plane, externally 

 whitish, reaching a diameter of 4-7 cm., the margin regular or 

 lobed; hymenium concave or nearly plane, even or undulated,
