Maebride: “Sporangia clustered, spherical or ovoid, large 
sessile or mounted on long thin strand-like stalks, blue-gray, 
violet-iridescent or cinereous, smooth or more often rugulose; 
the stipes when present poorly differentiated, as if thread-like 
filaments and strips of the plasmodium. often branched and 
always reclining or even prostrate; hypothallus none; capilli- 
tium a large-meshed open network of rather slender tubules, 
the nodes unequally developed, white with the enclosed lime'» 
spores not strictly adherent though not without some tendency 
to stick together, delicately warted, bright violet brown, 10-12 y.. 11 
Lister says that the plasmodium is chrome yellow, the spor¬ 
angia ovoid, subglobose, or confluent and lobed, sessile or on 
membranous straw-colored branching stalks; that the spores 
usually adhere in loose clusters of 7-10; that in some specimens 
in the Strassburg collection the spores show but slight indica¬ 
tion of clustering, in others this character is well marked. 
Massee, calling this species B. varia Massee, says that the stem 
when present is generally weak and decumbent, several often 
more or less grown together, pale yellow or reddish, springing 
from a well-developed hypothallus of the same color. 
I find the long, weak, thread-like, yellow stipes very distinc¬ 
tive ; there is no evidence of a hypothallus in one extensive group 
of specimens that I have, and in another small group a well- 
developed, thick, dark reddish hypothallus; the spores seem to 
have no tendency to cluster. I find spores 10/x, 12y, and some 
as large as 13 u in diameter. 
One piece of bark half a foot wide and a foot and a half long 
with the surface very nearly covered with the sporangia, and 
accompanying it a dead elm leaf having a large group, were 
found at Blue Mounds November 5, 1904. A small fine specimen 
from Algoma was found in October 1904.
