‘ The spores are very unequally divided, the smaller cell appearing 
like an umbo. 
LOPHIOTREMA VESTITA, N. sp. 
Perithecia closely gregarious, small, .014 to .02 inch broad, sunk 
in the wood, erumpent, conical, clothed with a slight tawny- 
ferruginous pulverulent tomentum, ostiola naked, black, sulterete 
or compressed ; asci clavate, .006 to .007 inch long, .0006 to .0007 
broad ; spores crowded, subfusiform, at first biconic and uniseptate,

Readily distinguished by the tawny, pulverulent tomentum of 
the perithecia. 
LOPHIOTREMA PARASITICA, N. sp. 
Perithecia crowded, subsuperficial, .014 to .02 inch broad, 
clothed with a minute subcervine pulverulent tomentum, becoming 
blackish-brown with age, the ostiola prominent, subterete or com- 
pressed, clothed like the perithecia; asci subclavate, .005 to .006 
inch long, .0006 to .0007 broad; spores crowded, at first biconic, 
then triseptate, constricted in the middle, colorless, .0012 to .0016 
inch long, .0003 broad. 
On old Hypoxylon Morsei. Elizabethtown. September. 
This and the preceding species appear to be peculiar by reason of 
the pulverulent tomentum of the perithecia. They would seem to 
constitute a distinct section of the genus.
