Xylaria digitata (Z.) Grev. 
Prostrate trunks of maple, Acer saccharinum. Adirondack moun¬ 
tains. September. 
This species is quite variable. Specimens growing in the same 
group and under the same conditions had the stroma terete or com¬ 
pressed, simple or divided above into two or more branches, or two 
or more would be united at the base only as if growing from a single 
starting point. Occasionally two clubs are confluent or grown 
together throughout their entire length. The apex may be either 
rather bluntly acute or acuminate and sterile, but sometimes it is 
obtuse. The stem may be either short or long and wholly glabrous 
or at the very base involved in mucedinous tomentum. The clubs in 
our specimens were very fragile when fresh. 
Var. tenuis n. var. Clubs slender, 1 to 1.5 lines thick, with the 
sterile apex commonly more conspicuous; perithecia less crowded 
and more prominent; stem elongated, commonly flexuous. 
This variety was found growing on the same trunk with the ordi¬ 
nary form but lower down on the sides and partly beneath, and 
probably depends chiefly on its place of growth for its peculiar devel¬ 
opment. The spores both in it and in the typical form are .0007 to 
.0009 in. long. 
Var. Americana differs chiefly in its shorter spores, which are about 
,0005 in. long. This is our most common form and the dimensions 
of its spores are given in the work on North American Pyrenomy- 
cetes as representing the spores of the species in this country. It 
may be a question whether this fungus would better be considered a 
variety of X. digitata or a distinct species.

NEW YORK SPECIES OF FLAMMULA. 
Flammula Fr. 
Pileus fleshy, its margin at first involute; lamellae decurrent or 
adnate without a sinus; stem fleshy-fibrous, not mealy on the upper 
part; veil fibrillose or none. 
The genus Flammula is not represented in our territory by a large 
number of species. It is, nevertheless, not very sharply distinct from
