Bean—The Myxomycetes of Wisconsin. 1295 
The specimens which we have show the same small, densely 
crowded sessile sporangia as T. persimilis and T. scabra. The 
color is yellow, rather lighter and somewhat nearer orange than 
the majority of the specimens of T. persimilis. The capillitium 
escapes from the peridia, forming a woolly mass above. So far 
the description is not distinctive. But I find the capillitium 
smooth, or with a few scattered, very minute spinules, 6-8/a 
thick, with the ends 6/x long. There are four spirals closely 
wound. The spores are more regular in outline than those of 
T. persimilis. the border is 1-2 y wide, not interrupted. The 
bands are reticulated, more even and narrower than in T. per¬ 
similis. and are neither pitted nor fragmentary; and the spores 
are larger, being 12-1 5/a in diameter. 
The smoother capillitium, the larger, regular spores with their 
even bands not fragmentary, render this species not difficult to 
distinguish from those of similar general appearance, when they 
have once been studied. 
We have specimens collected in Wisconsin in 1897, locality 
not given, and one from Star Lake, August 4, 1901 ; growing on 
dead poplar wood and bark.

Saccardo: “Sporangia clustered, stipitate, crowded, turbin¬ 
ate, from dull yellow to olive yellow; stipe plicate, the tube con¬ 
tinuous with the sporangial cavity; elaters spindle-shaped, simple 
or branched, 4-5/x in the widest part, tapering equally toward 
each end, the ends from four to six times as long as the diameter 
of the smooth thread; spiral bands 3, smooth, prominent; spores 
warted, 10-12/t.” 
Macbride’s description differs but little from that given above. 
He calls the color shining olive or olivaceous brown. He say3 
of the stipe that it is generally elongate, concolorous above, 
dark brown below, hollow, i. e. filled with spore-like cells. He 
speaks of the elaters as having long, smooth, unwound tips. The 
spores under the lens he finds to be pale, minutely delicately re¬ 
ticulate, 10—1.2/a in diameter.
