_ The prominent character in this species, as indicated by the name, is the 
 suleate stem. The furrows are very deep, and extend, without interruptio 
the entire length of the stem. The whole stem, as shown by a cross-section, 
is made up of the costze intervening between these furrows. I do not find the 
_ stem “stuffed,” as required by the description in Syst. Mye. Vol. ii, p. 15. a

_ One of our most common Revie agrees with the characters ascribed to 
this species, except in the size of the spores. These are described as .J007’ 
0008 long. In our plant they are about .0005 long. Because of its shores 
G spores, it has sometimes been referred to X. Hypoaylon ; but in this species

difference between its spores and those of X. digituta is so marked and so — 
constant that it should not be disregarded. I therefore propose to dishtigaa
