cles give a reticulate appearance to the dark-brown patches which 
ornament the snirface of the wall. ’ ’ 
In Maebride’s description are the statements that this is found 
in the same situations as L. epidendrum and at the same season; 
that this species is recognizable by its gregarious habit, small 
size, and dusky color; and that the little spheres are dark lead- 
colored, shading to black. 
Neither Massee, Lister nor Saccardo mentions this species. 
The specimens which I have agree with the above descriptions 
very closely. The aethalia besides being smaller than those of 
L. epidendrum, are of a dusky brown or nearly black color from 
the first. The irregular scales on their surface under the lens 
show 7 the vesicles as having nearly regular polygonal outlines, 
quite different from those in the peridium of L. epidendrum. 
The spores are smoother and not tinted with yellow 7 . The capilli- 
tilim threads I find to be from 3-9 ( u wide, and although preserv¬ 
ing the general appearance of those of L. epidendrum., yet the 
wrinkles in these are less deep. few r er, and are irregularly placed. 
We have but one specimen, which was found growing on decay¬ 
ing basswood, at Devil’s lake, July 2, 1904.

Maebride: “Plasmocliocarp bent or short-flexuous, often, arcu¬ 
ate or completely annular, dark chestnut brown or black, open¬ 
ing irregularly: peridium thin, brittle, translucent, covered with¬ 
out by a rather dense layer of brownish or blackish brown scales ; 
capillitium of long, sparingly branched threads furnished with 
projecting spinules remarkable for their length, about twice the 
diameter of the thread; spores yellow 7 , minutely but distinctly 
warted, about 12y. Tt is readily distinguished at sight by the 
peculiar annular, looped, and U-shaped plasmodioearps, with 
their dark umbrine or blackened surface.” 
Saccardo gives the diameter of the spores as 10.8 to 12.5/q 
capillitium threads as 2.5 to 3.3y thick, and spines on the thread 
as 1.7 to 3y long. 
Massee says the sporangia dehisce in a circumscissile manner. 
He describes the threads of the capillitium as densely and very
