Duranp: Stupies 1n NortH AMERICAN Discomycetes 459 
8, brown, minutely verrucose, broadly elliptical, 18-25 x 9-15 4; 
paraphyses numerous, longer than the asci, hyaline, septate, fili- 
form, curved or circinate, sometimes irregularly knobbed at the 
apex, imbedded in a greenish-yellow jelly. 
On burnt wood and soil, New York, Durand, nos. 984, 985, 
994, 992; W. Virginia, Nuttal//. Reported also from California, 
on dung, Harkness & Moore, and from Nebraska, on wet sandy 
ground, Clements. 
This species was described from specimens collected in Eng- 
land, on charcoal beds. It has been found elsewhere in similar 
situations in France, Germany and Switzerland. In September, 
1900, it was my good fortune to find numerous plants of this 
species growing in a burnt-out swamp, near Canandaigua, N. Y. 
The ascomata were in all stages of development, and were attached 
to burnt wood and adjacent burnt soil. The above description 
was drawn from fresh plants. I have compared the specimen in 
N. A. F. no. 2908 with that in the Elv. Brit. no. 47, in my her- 
barium, and find them identical.

Plants usually solitary but occasionally clustered, nearly sessile 
or with a short thick stem, attached by a yellowish mass of 
mycelial threads to the soil which it binds together. Ascomata 
cup-shaped, bowl-shaped, or rarely spread out flat, usually with 
€ margin slightly incurved, commonly regular but often con- 
torted or split at the margin, 0.5-2.5 cm. in diameter ; disk clear 
yellow or orange-yellow, externally yellow at first but becoming 
greenish, finally yellowish-olive, smooth or pruinose. Excipulum 
entirely parenchymatous, cells small, the cortical ones rounded, 
10-20 # in diameter, the medullary ones elongated and irregular, 
showing their hyphal origin. Hymenium about 4 the total 
thickness of the cup below. Asci narrowly clavate-cylindrical, 
@pex rounded, not at all blue with iodine, 125-150 x 9-IO#; 
Spores 8, uniseriate or subbiseriate, hyaline, smooth, globose, 5-8 
diameter. Paraphyses slender, filled with orange granules above.
