.... hypothallus white, often wide extending. Easily 
distinguished by its brown color and smooth, shining, though un¬ 
even surface.” 
Lister does not differ from the above quoted descriptions. 
The foregoing descriptions are very satisfactory. I have 
found small specimens of this species growing in the midst of 
Lycogala epidcndrum of about the same size. There was, how¬ 
ever no difficulty in distinguishing them. The Enteridium ro- 
zeanum has generally a broader base, and always more or less 
of a thin light brown, often white, hypothallus partly or wholly 
surrounding it. The surface, too, is more irregular and of a 
redder brown than the Lyc-ogala. Many are pulvinate and lobed. 
Those I have vary from % to 6 cm. in length. I find the spores 
to be more regularly globose than those of Reticularia ly coper- 
don, and with less of the surface reticulated—not more than 
half, with the rest of the spore minutely roughened; spores 
7-9 ix 
We have two specimens from "Wisconsin which do not have 
the exact locality and date given; another from near Webster on 
dead wood, collected in the summer of 1894; one from Blue 
Mounds, October 4, 1902; three from Madison, 1901; several 
marked Madison, October 14, 1897; several Madison, October 19, 
1901; and a large number from the cemetery woods, Madison, 
October 20, 1903. Many of the latter show large tubules, whit¬ 
ish inside, extending to or above the surface, which have been 
made by insects. In some of these tubules the dead insect is 
still to be found. 
Macbride says in his description, ‘‘capillitium none,” yet on 
Plate I. of the same book he gives a figure which he, on the op¬ 
posite page, calls the capillitium of this species. The illustra¬ 
tion agrees with the structure which I find in the interior of the 
sethalia.

Saccardo: ‘‘JSthalia nude, upon a common well-developed 
hypothallus, cortex very early becoming dry and dark, thick, 
brown, shining, wrinkled: spore-mass ochraceous or umber-
