4. Scoleconectria polythalama (Berk.) 

 Nectria polythalama Berk. ; Hooker's Fl. N. Zealand 2 : 203. 



1853- 



Nectria auriger Berk. & Rav. Grevillea 4: 46. 1875. 

 C 'alone etna polythalama Sacc. Michelia 1 : 308. 1878. 



Perithecia erumpent in dense clusters 1-2 mm. long and about 

 1 mm. broad ; seated on a yellowish stroma ; individual perithecia 

 subglobose, at first covered with a yellowish-green coat of 

 powdery material which finally disappears leaving the perithecia 

 of a dull red color, finally collapsing; asci cylindrical or clavate, 

 50-60 X 12-15 mic, 8-spored; spores crowded, elliptical, curved, 

 yellowish-hyaline, 7-septate (mostly), 18-22 X 5 mic. 



On Chionanthus, Fraxinus and Liquidambar. 



Type locality : New Zealand. 



Distribution : Virginia to Alabama. 



Illustrations : Brekeley, Hooker's Fl. N. Zealand 2 : pi. 116, 

 /• i5- 



Exsiccati : Ellis, Fungi Nova Caesareenses, 6g; Ellis, N. Am. 

 Fungi, 79; Ravenel, Fungi Car. Exsicc. 54, 60. Other specimens 

 examined : Virginia, Commons. 



The perithecia are greenish in some specimens and reddish in 

 others, the difference in color being due to the presence or absence 

 of the greenish powdery material with which the perithecia are 

 clothed. This difference in color seems to have been the dis- 

 tinguishing character of the two species, N. polythalama Berk, 

 and N. auriger Berk. & Rav. 



5. Scoleconectria balsamea (Cooke & Peck) 

 Nectria balsamea Cooke & Peck, Ann. Rep. N. Y. State Mus. 26 : 



84. 1874. Grevillea 12: 81. 1884. 

 ? Calonectria Cucurbitula Sacc. Michelia 1 : 312. 1878. 

 Calonectria balsamea Sacc. Syll. Fung. 9: 986. 1891. 



Perithecial clusters small, 1-2 mm. in diameter, erumpent 

 through the outer bark; individual perithecia nearly globose 

 smooth or only minutely rough, red; in dried specimens dull 

 brick-red, entirely collapsing, becoming pezizoid; asci cylindrical 

 to clavate, at first filled with numerous minute, spore-like bodies 

 about 2X1 mic. among which are several (2-4) true spores; 

 spores fusiform, 5-6-septate, granular within, 15-25 X 4~5 mic -
