Macbride adds a very important distinction—that the caly- 
culns is more or less distinctly marked by fine delicate radiating 
venules. He finds that the net forms rather large three- to five¬ 
sided meshes with small, irregular, brownish nodules and show¬ 
ing only here and there a free extremity. He also states that 
this species is generally recognized by the large sporangia, 0.5- 
0.9 mm, the comparatively short stipe, simple net, and more or 
less orange color, the colour being uncertain. 
Lister describes the calyculus as one-third the height of the 
sporangium, and beset with round plasmodic granules 0.5 to ly. 
in diameter, arranged in close lines radiating from the base. I 
find this, description very good for the character of the caly¬ 
culus. 
Massee adds that the sporangia are scattered, which I find 
to be true. They are never crowded. 
My specimens agree with the above quoted descriptions. 
Among the ripe sporangia I found a small quantity of little 
intensely black and shining droplets, which may have been im¬ 
mature sporangia. Many of the ripe ones which had not lost 
their spores had a tiny black spot on top. I tried to induce the 
black droplets to develop in a moist chamber, but they at once 
became covered with a white mold and failed to develop. 
I made a large collection of this species from a decayed oak 
stump at Elmside, Madison, July 15, 1904.
