13. Nectria sulphurea (Ellis & Calk.) Sacc. 

 Syll. Fung. 9 : 966. 1891 



Dialonectria sulphurea Ellis & Calk. ; Ellis & Everh. Jour. Myc. 

 4:57. 1888. 



Perithecia scattered, sulphur-yellow-pruinose and seated on a 

 sulphur-yellow-pruinose base 1 or more cm. in diameter, often 

 becoming reddish-brown with age, 200 mic. in diameter ; asci 

 evanescent; spores small, fusoid with the ends obtusely pointed, 

 i-septate and constricted at the septum, often with an oil-drop in 

 each cell, 7-12 X 3-4 mic - (P l - 5- /• 



Parasitic on old fungi, Stereum. 



Type locality : Jacksonville, Florida. 



Distribution : Ohio to Florida. 



Exsiccati : Ellis & Everhart, N. Am. Fungi, 1947. Other 

 specimens examined : Florida, Calkins (type) ; Ohio, Morgan.. 



Distinguished by the sulphur-yellow-pruinose perithecia and 

 the sulphur-yellow-pruinose base, as well as by the habitat. 



While the perithecia are seated on the yellow base this does 

 not resemble a stroma but the substratum seems to be stained 

 being of the same color as the perithecia themselves. In both 

 specimens examined it has been impossible to make out an ascus 

 but the arrangement of the spores seems to indicate its presence. 



14. Nectria truncata Ellis, Am. Nat. 17 : 194. 1883 



Perithecia minute, 125-150 mic. in diameter, gregarious, yel- 

 lowish (dried specimens almost white), slightly collapsing, be- 

 coming subtruncate, or with the ostiolum still more depressed so 

 as to appear umbilicate; asci when young tapering into a rather 

 pointed apex, finally clavate, 8-spored, 35-40 X 5 mic. ; spores 

 crowded, fusoid, i-septate, slightly constricted, 12 X 2-3 mic. 

 (pi. 5. /• 14). 



On the inside of white cedar bark which has been stripped from 

 the tree. 



Type locality : Newfield, New Jersey. 

 Distribution : Known only from type locality. 

 Exsiccati: Ellis, N. Am. Fungi, 1332. Other specimens ex- 

 amined: Newfield, New Jersey, Ellis (type). 



Distinguished by the small, pale perithecia and minute spores.
