of Sassafras, Carolina (Schw.), on branches of Rhus venenata, New 

 Jersey (Ellis).

" Innate, prominent, pustules in confluent parallel series, stroma 

 cortical, circumscribed; easily recognized from its manner of growth, 

 longitudinally erumpent and confluent; even the perithecia in the 

 pustules seriately arranged. Conceptacle obliterated. 



On branches of Juglans alba, Carolina/' (Schw.). 



Specimens sent under this name by Peck from Troy, N. Y., on 

 Juglans, agree with the diagnosis of Schweinitz quoted above, only 

 the perithecia are not seriately arranged in the pustules, but irregu- 

 larly circinate, and there is no discoloration of the bark or any circum- 

 scribing line. The perithecia in the Troy specimens are numerous, 

 10-16 in a pustule, small (J mm.). Ostiola short, obtuse, hemispherical, 

 sulcate, erumpent in small, seriate fascicles rising but little above the 

 epidermis, which is raised into little seriate pustules so close together 

 as to form almost continuous, close-lying, longitudinal ridges. Asci 

 clavate, about 40x6 p.. Sporidia crowded-biseriate, about 7 x 1 J 2 fz. 



Notwithstanding the slight discrepancies, this seems to be the 

 species described by Schweinitz. 



Var. juglandina (Valsa juglandina, C. & E. Grev. V, p. 92), 

 differs only in the pustules being scattered or only subseriate, and 

 perithecia mostly only 3-8 in a pustule. We make the sporidia 6-$ x 

 H-2// (10-15x3/2, Cke.). 



Eu. scoparia, (Schw.) 



SphcBria scoparia, Schw. Syn. Car. 101, id. Syn. N. Am. 1318. 

 Valsa scoparia, Stevenson, 1. c. 

 Eutypella longirosiris, Pk. 

 Exsicc. EH. & Evrht. N. A. F. 2d Ser. 2517. 



Stromata cortical, orbicular, 2-4 mm. diam., often confluent, sur- 

 rounded by a thin, black stratum, showing a distinct, black, circum- 

 scribing line on a horizontal section, raising the bark but slightly. 

 Perithecia 5-12 in a stroma, buried in the scarcely altered substance 

 of the bark, globose, about J mm. diam., black and polished inside, 

 with coriaceous walls, contracted above into slender necks terminating 

 in a close fascicle of more or less elongated, cylindrical, deeply 4-5-cleft 

 ostiola. Asci clavate, p. sp. 18-22 x 4 //. Sporidia crowded, allantoic!, 

 minute, strongly curved, yellowish-hyaline, 4 x 1 p, with a nucleus in 

 each end. 



On dead elm branches, Canada to Missouri. 



Agrees with specimens in Herb. Schw.
