Spore-sac Fungi—Ascomycetes 
Vibrissea circinans 
Vibrissea circinans is a pale yellowish flesh colour, or simply 
yellowish fleshy fungus found growing in circles or clusters, 
with convex caps and incurved, wavy margins, the concave under 
surface often minutely wrinkled. The stem is long, pallid, or 
reddish. The plant is found chiefly in pine woods. 
GENUS MITRULA 
The genus Mitrula has the spore body erect, black or bright 
coloured, and dry, spatulate, or cylindrical, often compressed lat- 
erally. The spore-bearing surface is sharply distinct from the 
scaly or mealy stem below. 
Irregular Mitrula (Edible) 
Mitrula vitellina, var. irregularis * 
Spore Body—Bright egg yellow. Club-shaped, somewhat lobed, 
cylindrical or compressed ; apex narrow, obtuse, smooth. 
o two plants are quite alike. Length, 1-2 inches. 
Stem—Short, white, rather distinct, covered with fibres. Spongy 
and white within. 
Hatitat—In mossy places in woods during the autumn. The 
specimen pictured was found growing among fallen birch 
leaves, hemlock needles, and moss, in the dense woods at 
Lake Placid. 
FAMILY HELVELLACEA:—MORELS 
A second family Helvellacee contains three important gen- 
era, Morchella, Gyromitra, and Helvella, in which are the largest 
and most highly prized spore-sac fungi known. They are dis- 
tinguished from the earth-tongues by the cap-like form of the 
spore body or ascoma, but especially by the character of the 
spore-sac, which opens by a little lid instead of by a simple pore.
