XYLARIA ACUTA 22. Sp. 
Plant gregarious or subcespitose, 1-1.5' high; club cylindrical 
or subfusiform, generally with a sterile acute apex, blackish-brown, 
central substance white with a radiating structure; stem involved 
in a dense purplish mucedinous tomentum which causes it to 
appear bulbous; perithecia globose, black ; spores uniseriate, ellip- 
tical, abmmesithes slightly curved, conaréa, 0006" .0007' long. 
Mossy decaying logs in WOH Greig. September. 
This species is related to Y. digitata from which it differs in its 
less czespitose habit, and in the character of the stem and central 
substance. According to Fries, A. digitata has a “simple central 
pith,” in this species “the central pith is radiating as in XY. poly- 
morphea.
