Pennsylvania specimens nor those in Rav. Car. show anything of the 

 ■'white lanose patches 2 in. or more in diameter." 



N. diploa, B. & C. Journ. Linn. Soc. X, p. 378. 



Perithecia cespitose, minute, ovate, subfurfuraceous, at length col- 

 lapsing, light red, pai'asitic on some erumpent Valsa? Asci subsessile, 

 oblong-cylindrical, about 65 x 10 ft. Sporidia obliquely uniseriate, 

 oblong-elliptical, endochrome finally divided in the middle, 20-25 x 

 9-11 p., hyaline or nearly so. In some of the asci, the sporidia are 

 partially biseriate and somewhat smaller. 



On bark of alder, South Carolina (Ravenel). 



The description here given is from an examination of the speci- 

 mens in Rav. Fungi Caroliniani, III, 55. In these specimens the 

 nuclei have disappeared and the underlying (Valsa f) is so completely 

 covered by the perithecia of the Nectria as to be easily overlooked. 

 Differs from the preceding species in its more compactly clustered and 

 less prominent perithecia, and its larger sporidia. 



Var. diminuta, Grev. IV, p. 46, is (sec. Cooke) a Galonectria 

 with 3-septate sporidia. See p. 114 of this work. 



N. verrucosa, (Schw.) (Plate 12) 



Sphesria verrucosa, Schw. Syn. N. Am. 1401. 

 Spharia dematiosa, Schw. 1. c. 1424 (?) 

 Nectria verrucosa, Sacc. SyU. 479. 

 Exsicc. Rav. F. Car. I, 52.— Ell. & Evrht. N. A. F. 2d Ser. 2371. 



Perithecia cespitose, globose, about \ mm. diam., verrucose- 

 roughened, light bi'ick-red, becoming much darker and finally collaps- 

 ing above, more or less distinctly clothed with weak, short, rudi- 

 mentary, hyaline, glandular hairs, seated on an orange-red, concave or 

 depressed stroma {Tuhercularia), forming groups 1-2 mm. diam., at 

 length more or less deciduous. Asci oblong-cylindrical, with a short, 

 substipitate base, 60-70 x 10-12 /^. Sporidia biseriate, oblong, uni- 

 septate, 12-18x4-5 ji. The stroma, as in most other Nectrias, is 

 finally hidden and partially obliterated by the perithecia. 



Common on Morus and Sassafras, Pennsylvania (Scjhweinitz), 

 on Morus, Melia, etc.. South Carolina (Ravenel), and on Moras, New 

 Jersey (Ellis). 



Differs from N. cinnabarina in its concave, scarcely prominent 

 stroma, the peculiar roughening of the perithecia, and in its shorter 

 asci, and mostly narrower sporidia. N. coccinea has the perithecia 

 nearly smooth, or when dry, slightly furfuraceous.
