here the elater is narrow and the sculpture obscure/ ’ 
Lister speaks of the sporangia as sometimes forming short 
plasmodicarps, and speaks of the wall as membranous, pale yel¬ 
low, marked with ring-shaped or crescentic thickenings. He 
gives the diameter of the spores as 11-16/x. 
Massee describes the spores as turbinate or subglobose, the 
elaters as rarely branched, and sometimes swollen at the com¬ 
mencement of the tapering tips. 
The abundant material which I have varies from crowded to 
scattered, from short-stipitate to sessile forms, from dark orange 
to shining bronze-brown, from globose to plasmodiocarpous 
forms, and varies considerably in size even in the same group. 
One of my groups has a distinct hypothallus. The elaters are 
generally simple, sometimes branched, 3-5 y thick, the spirals 
smooth, 2 or 3 projecting boldly, continuing to near the end of 
the tip. With but one or two exceptions, all the elaters I have 
seen have been swollen just at the beginning of the apex, gener¬ 
ally on one side, giving the end a bent or unsymmetrical appear¬ 
ance at once noticeable and determinative. The tip is curved, 
often twisted like a corkscrew. The spores I find to be globose, 
delicately warted, 12-16/x. 
Many specimens I found in the cemetery woods late in October 
1903. Some were found in Vilas woods and in the campus 
woods in 1903, and in two other localities in Madison in 1899. 
They were mostly on dead poplar wood and bark.
