Cups scattered, sessile, turbinate, then plane; exter- 
nally black, and clothed with a black byssoid tomentum ;

Winter, “ Fungi Eur.,” 2211; Rehm, “ Asco.,” 705. 
On dead leaves of Pinus sylvestris. 
Cups about 24 lines broad. This appears at first as 
a minute, hairy Chetomiwm-like body, nearly black, after- 
wards expanding into a sublentiform disc. The brown 
hairs of the hymenium, being prolongations of the para- 
physes, give this plant a striking character.

needles.
