is deep red and a plasmodicarpous fructification occasionally ap¬

Massee speaks of the capillitium mass as elongating at maturity 
and carrying the apical portion of the sporangium at its apex, 
where it remains in the form of a cap. I think this characteristic 
is not universal in this species. He says the capillitium tips are 
usually marked by from one to three short, smooth spines. This, 
too. I find not common. He says the spores vary from almost 
perfectly smooth to minutely but distinctly warted. 
Lister gives the length of the capillitium spines as 2-5/x. He 
says the capillitium is rarely nearly smooth, and that sporangia 
are occasionally found with a few free elaters pointed at each 
end, in addition to the continuous network of threads of the 
usual type. 
I find no essential points in which my specimens differ from 
the above descriptions. I have failed to find plasmodiocarpous 
forms. The spores are distinctly warted, from 9-12/x in dia¬ 
meter. 
This species is very common here. It was found in great abun¬ 
dance late in October 1903, in the cemetery woods, in Vilas woods, 
and in the university campus woods. We have specimens also 
from Blue Mounds, collected October 4, 1902. A few collected 
at Blue Mounds April 14, 1904, were evidently the fruit of the 
previous year. Others are from Blue Mounds, July 1, 1908, and 
from Sturgeon Bay, on dead wood, August 19,1905.

Of the four authorities whom I have before quoted, only Mac- 
bride and Lister mention this species. 
Macbride: “Sporangia distinct, crowded, cylindric or irregu¬ 
lar, overlying one another, rich copper-colored, metallic, shining, 
becoming browm, stipitate; the peridium thin, the upper portion 
early evanescent, the base persistent as a cup, as in Arcyria; cap¬ 
illitium concolorous, the thread abundantly branched to form a 
loose net, with many free and bulbous ends, pale under the lens, 
marked by three or four somewhat obscure spiral bands, and a 
few wart-like or plate-like thickenings; stipe very short; spore-
