Apothecia scattered, sessile, at first cup-shaped, soon becom- 

 ing discoid, fleshy, circular in outline not usually exceeding 1.5 

 cm. in diameter ; hymenium dark brownish-black, slightly concave 

 or nearly plane ; asci cylindric or subcylindric, reaching a length 

 of 200 fx and a diameter of 18 p, 8-spored ; spores obliquely 1 -seri- 

 ate, with the ends overlapping, narrow-ellipsoid to fusoid, often 

 with a small apiculus at either end, becoming pale brownish and 

 often delicately sculptured, about 10 X 24 /x, containing two large 

 oil-drops ; spore sculpturing consisting of minute warts ; paraph- 

 yses slender, adhering together at their apices, dark-brown. 



On damp soil. 



Type locality: Italy. 



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

3. Discina convoluta Seaver, sp. nov. 



Apothecia gregarious or cespitose, very short-stipitata, becom- 

 ing 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 dis- 

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

 not more than 1 cm. long, whitish, deeply corrugated ; asci cylin- 

 dric or subcylindric, reaching a length of 400-500 ju, and a diam- 

 eter of 20 fx, 8-spored but a part of the spores often remaining 

 undeveloped ; spores i-seriate, with the ends usually overlapping, 

 ellipsoid, becoming sculptured and appendiculate, 12-14 X 

 35-40 jx; spore-sculpturing consisting of warts or short inter- 

 rupted ridges which often approach very fine reticulations ; spore 

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

 raphyses stout, usually straight, reaching a diameter of 8 /*. at 

 their apices, densely filled with yellow granules.
