enlarged above, embedded in golden-yellow mucilaginous sub-

On damp soil. 



Type locality: The New York Botanical Garden. 



Distribution: New York to Iowa and Colorado.

This species has been mistaken for Ascoholus viridis of Europe 

 which is very different in spore characters (see Plate 7). 



Since the above account was prepared, a fine specimen of this 

 species has been received from Dr. G. R. Bisby, who collected it 

 on damp soil at the Agricultural College in Winnipeg, Canada.

 (Plate 7, fig. 3.) 



Apothecia gregarious or thickly crowded, at first nearly 

 globose, expanding and becoming almost discoid, reaching a 

 diameter of 3-5 mm., externally smooth, greenish-yellow; hy- 

 menium plane, convex or irregularly convolute, at first similar in 

 color to the outside of the apothecium, becoming dotted over 

 with the ends of the protruding asci, finally entirely black; asci 

 subcylindric to clavate, gradually tapering below into a stem-like 

 base, 8-spored; spores at first 1 -seriate, becoming crowded and 

 partially 2-seriate as they mature, at first hyaline and containing 

 one oil-drop which is often surrounded by numerous smaller 

 ones, becoming violet, finally almost black and opaque, becoming 

 sculptured, reaching a diameter of 18-20 /x or 18 X 20 m; spore- 

 sculpturing taking the form of numerous vein-like reticulations, 

 which consist apparently of crevices, the spaces between the 

 crevices giving rise to prominent projections visible about the 

 periphery of the spore, the spaces between appearing as notches, 

 giving the spore a very ragged appearance; paraphyses scarcely 

 enlarged above, embedded in golden-yellow mucilaginous sub- 

 stance. 



On damp soil in woods and on the margin of a small pond. 



Type locality: Woods near Yonkers, New York. 



Distribution: Known only from the type locality.
