Italy, Russia, United States (Forestburgh, N.Y., Peck , n. 320), 
Tasmania (Rodway ; on small twigs of Eucalyptus ). 
The spores are distinctly 1 -septate in a specimen named by Persoon, 
and also in British specimens collected at Carlisle by Dr. Carlyle. 
Phil ., Elv. Brit. n. 2, and Ellis , N. Amer. Fung. n. 433, quoted by 
Rehm (Kr.-Fl. n. 5861) under the present species, belong, in both 
instances, to Mitrula laricina . Mitrula pusilla , Fr., growing on fallen 
leaves of Pinus silveslris, differs from the present in its slightly smaller 
asci and spores, and is perhaps only a small form of M. cucullata. 
Mitrula sphaerocephala , Bres., also occurring on larch leaves, differs 
from M. cucullata in its much thicker spores. 
Mitrula pusilla, Fries , Syst. Myc. i, 493, 1821 ; Sacc., Syll. viii, 
n. 101, 1889; Rehm, Kr.-Fl. n. 5862, 1896; Boudier, Bull. Soc. 
Myc. France, ix, 10, pi. 2, f. 4, 1893. (PI. XII, Figs. 47-49.) 
Gregarious ; entire fungus 4-7 mm. high ; ascigerous portion 
clavate or subglobose, glabrous, rusty yellow, -5-1-5 mm. high, 
with a slight indication of a lower free margin encircling the stem, 
which is filiform, usually crooked, yellow, brownish and downy at 
the base. Asci narrowly clavate, pore blue with iodine, 45-56 x 6 /*; 
spores 8, 1 -seriate, or inclined to be 2-seriate above, hyaline, 
smooth, continuous, fusiform, ends acute, often slightly bent, 12-15 x 
2-5 /x; paraphyses filiform, tips slightly thickened.
