Cespitose, stroma cortical. Perithecia crowded, superficial, pur- 

 plish, at length collapsing or laterally compressed. Asci oblong, sessile, 

 8-spored, 60-75 x 12-16 fi. Sporidia biseriate, ovate, elliptical or sub- 

 pyriform, subobtuse, somewhat curved, 3-septate, pale yellowish, 18-20 

 x 6-8 /i. The conidial stage is considered to be Fusarium sambu- 

 cinum, Fckl., or F. roseum, Lk. This is quite a common species and 

 is found on bark of dead limbs of various deciduous trees and on dead 

 herbaceous stems especially on dead stalks of Zea Mays and also on 

 the grain. 



Tulasne, Sel Carp. Ill, p. 68. enumerates as conidia of this species, 

 Fusarium roseum,, Lk., F. incarnatum, (Rob,), F. aurantiacum, 

 Lk., Selenosporium sarcoehroum and S. lateritium,, Mazerio.

Perithecia gregarious, confluent-cespitose and concrescent, coria- 

 ceo-membranaceous, verrucose, at length flaccid, plicate, ovoid, subcon- 

 tracted at the base, bluish, 200-300 x 170-220 /;, papillate. Asci ob- 

 long-lanceolate, acuminate above, contracted at the base into a short, 

 thick stipe, 8-spored, 60-76 x 10-12 /i. Sporidia uniseriate or sul tin- 

 seriate, fusiform, curved or straight, subacute, 3-septate, but scarcely 

 constricted, nearly hyaline, 18-24 x 4-5 fi. Conidial stage, Fusarium 

 roseum, Lk. The characters of this species, as here given, are taken 

 from Sacc. Sylloge. From the specimens at our command, we have 

 always found it difficult to separate this from the preceding species.
