spores colorless, even, broadly ovoid, somewhat flattened on 
one side, 43 x 23-3 y. 
Fructifications about 2-3 mm. high; pileus 1-2 mm. broad; 
stem 1 mm. long, mm. thick. 
On living stems of herbs іп damp places. New York. Sep- 
tember. Rare. 
Тһе minimum dimensions given above for the fructifications 
are about those of European specimens of this species as figured; 
the American specimens run rather larger in Peck's collection. 
Peck noted that some of his specimens were white when col- 
lected, but that they dried yellow like the others of the collec- 
tion. In other respects our American specimens agree closely 
with the figures and description of European specimens. Oude- 
mans gives the spore dimensions as 10-12 x 4-5 y, but Patouil- 
lard gives them as they are in American specimens. 
Specimens examined: 
New York: Griffins, Delaware Co., C. H. Peck (in Coll. N. Y. 
State). 
2. C. læta Fries, Epicr. 568. 1836-1838. 
Illustrations: Patouillard, Tab. Anal. Fung. f. 362. 
Fructifications membranaceous, obliquely cup-shaped, ex- 
tended at the vertex into a stem, pendulous, entire, everywhere 
glabrous and sulphur-colored; stem straight or somewhat flexu- 
ous, hymenium minutely pitted; spores colorless, even, 6-8 x 
3-4 џ, borne four to a basidium. 
Fructifications 3-5 mm. high, 2-4 mm. broad; stem 1-2 mm. 
long, about 3 mm. thick. 
On dead stems of large herbs lying on the ground. New York. 
August. 
Fries described the fructifications as 6-8 mm. broad; the 
dimensions given above are those of Patouillard’s figures 
and of the specimens collected by Peck. Patouillard notes 
that the specimens blacken when old; Peck states, “The 
beautiful sulphur-color is lost in drying.” The pitted 
surface of the hymenium is a noteworthy character of C. leta 
and this and the larger spores of C. leta distinguish it from C. 
sulphurea. 
Specimens examined: 
New York: East Berne, C. H. Peck (in Coll. N. Y. State).
