Mycologia 



is darker, clothed externally, except the ostiolum, with a dense 

 covering of delicate, hyaline hairs which are 2 mic. in diameter 

 and 10-20 mic. long; asci narrowed above and below, 20-25 X 

 5-6 mic, 8-spored; spores mostly 2-seriate, minute, 6-7 X 1.5-2 

 mic, i-septate, sometimes very slightly constricted (pi. 5. /. 7). 



On rotten wood. 



Type locality: New Jersey. 



Distribution : Known only from type locality. 



Specimens examined: New Jersey, Ellis (type). 



Distinguished from the preceding by the smaller perithecia and 

 slightly larger spores. 



This and the preceding species very closely resemble each other 

 both in external and internal characters, however there seems to 

 be a slight difference so the two are here allowed to remain as 

 distinct.

 Myc. 3: 116. 1887 



Perithecia scattered or gregarious, superficial, subglobose, 80 

 mic. in diameter, smooth or with a few poorly developed hair- 

 like outgrowths, at first pale, becoming orange; asci broad- 

 clavate, 35-40 X 12 mic, 8-spored ; spores irregularly crowded, 

 cylindrical-allantoid, hyaline or subhyaline, i-septate, scarcely 

 constricted at the septum, 14-18 X 2-3 mic (pi. 5. /. 8). 



Parasitic on the thallus of some lichen, on dead limbs. 



Type locality : Newfield, New Jersey. 



Distribution : New Jersey. 



Specimens examined: New Jersey, Ellis (type). 

 Distinguished by the allantoid spores. 



In the original description of this species Mr. Ellis states: 

 " The species has been observed now for the past eight years and 

 seems to be quite distinct from any of the other lichenicolous 

 species." He also stated that the thallus of the lichen Parmelia 

 tiliacea (?) turns dull red (bright red within). The spores in 

 the specimens examined by the writer are pale reddish but Mr. 

 Ellis describes them in the fresh material as being hyaline.
