Growing on ground among moss. 

 Coll. W. G. Stover, April 30, 1908. 



Subgenus V. Geopyxis. 



Apothecia usually in groups, cup-shaped, fleshy, sessile later 

 stipitate, closed and spherical, later plane, exterior smooth. 

 Paraphyses branched at the base, septate, often enlarged upward 

 and colored. Asci cylindrical, ends usually rounded. Spores 

 elongated or elliptical, smooth, simple, with or without a large 

 central oil globule. 



Pezisa ncbulosa Cooke Mycog. 163. f. 281. 1879. 



Apothecia scattered, 0.5-1 cm. broad, dull gray in color, at 

 first cup shaped become almost or entirely plane, stipitate. Stipe 

 1 cm. or less in length, about 2 mm. in diameter, expanding into 

 the cup. Hymenium slightly brownish, hypothecium and ex- 

 ciple dull gray. Paraphyses filiform, slender. Asci cylindrical. 

 Spores usually fusiform, guttulate, 30-35 mic. long and 7-8 mic. 

 wide. 



Growing on old wood in very wet places.

 6, 1908. 



Genus II. Lachnea Quel. Bull. Soc. Myc. Fr. 25:291. 1878. 

 Type species, Lachnea fimbriata Quel. 



Mycelium within the substratum. Apothecia fleshy or 

 somewhat waxy, sessile, at first closed, becoming plane or con- 

 cave, exterior or at least the edge pilose or tomentose, hairs dark, 

 variously colored. Paraphyses linear or clavate, frequently filled 

 with colored granules near the apex. Asci cylindrical, usually 

 long, hyaline. Spores 8, elliptic or oblong, smooth or rough, 

 often biguttulate and minutely granular, hyaline. 



Growing on the ground, decaying wood or other organic 

 material. 



Structure of the cup is similar to that of Peziza but dis- 

 tinct from that genus by the hairy exterior or edge of the cup.
