 panding and becoming discoid, whitish with a tinge of pink, 

 reaching a diameter of 1-2 mm.; hymenium sHghtly concave or 

 nearly plane; asci cylindric or subcylindric, 8-spored; spores 

 obliquely 1-seriate, fusoid, each containing one or two oil-drops, 

 reaching a size of 10 X 30 /x; paraphyses slender, only slightly 

 enlarged above. 



On the ground. 



Type locality: South Carolina. 



Distribution: Known only from the type locality.

Apothecia gregarious or more commonly crowded, sessile, at 

 first closed and hemispherical, finally expanding and becoming 

 scutellate, reaching a diameter of 5-8 mm.; excipulum giving 

 rise above to a palisade of parallel mycelial threads, the ends of 

 which give to the border of the apothecium a minutely downy 

 appearance, the ends of the mycelium; hymenium orange, a little 

 darker than the exterior; asci cylindric above, tapering below 

 into a stem-like base, 8-spored; spores obliquely 1-seriate, 

 hyaline, smooth, containing one or two oil-drops, fusoid, 8-11 

 X 26-30 m; paraphyses septate, strongly enlarged above, reaching 

 a diameter of 8-10 ix at their apices. 



On the ground among mosses and in plant-pots.

The species described under this name has been reported by 

 Clements from Nebraska. A fine collection obtained March 19, 

 1928, on well-manured soil in pots in greenhouse of The New 

 York Botanical Garden has been referred here. Our plants 

 reach a diameter of 5 mm. and as they expand they split so that 

 the margin appears crenulate with a whitish border but scarcely 

 pubescent. The spores are a little broader than usually indi- 

 cated for this species. The color of the hymenium is a dirty-
