Lister’s description agrees with those already given excepting 
as to the size of the spores, which he gives as 5-7/* in diameter. 
Massee finds the diameter of the capillitium thread 8-12/*, its 
tube soon collapsing; he finds the spores minutely but distinctly 
warted and from 4 to 6/* in diameter. 
The above descriptions are fairly correct for my specimens. 
I find the capillitium to be of long, branching, anastomosing 
tubes from 3 to 21 /* thick, wrinkled, with free ends which are 
elavate, spherical, or merely rounded off. The spores are min¬ 
utely roughened, 6-7/* in diameter. 
We have specimens from upwards, of a dozen different locali¬ 
ties in the state, including the Lake Superior region. This species 
seems to be one of the most common and most plentiful. We have 
it collected April 29, 1904, at Blue Mounds, evidently just grown. 
We have collected it in July, October, and November. We have 
three groups of asthalia growing on three different species of 
Polyporus, one on wood charred by fire, on cedar, oak, and poplar, 
both on wood and bark, and on moss and the decayed wood on 
which the moss is growing.

Mlthalia spherical, surface opaque, smooth or indistinctly retic¬ 
ulate, brownish-gray; spore and capillitium-mass brownish- 
gray; spores delicately minutely spirmlose 3.3-5.8/* in diameter, 
of a faint clay color. 
Macbride speaks of the aethalia as solitary or two or three 
together, 2-4 cm. in diameter, purplish-giray or brown, smooth, 
shining; the peridium showing two or three layers in microscopic 
section; capillitium of abundantly branching, irregular, trans¬ 
parent tubules, marked by numberless warts and transverse 
rings or wrinkles; he calls the spore-mass yellowish gray, the 
spores by transmitted light colorless, smooth or faintly reticulate 
or roughened, 5-6/* in diameter. He says this species is generally 
mistaken for a puff-ball.
