On dead peach and. plum trees, common. Also at Newfield, N. J. 

 on Pyrus arbutifolia.

Valsa pulchelloidea, C. & E. Grev. VI, p. 92.

Perithecia about 300 /i diam., subglobose, brownish-black, seated 

 on the surface of the inner bark, in loose groups of 30-50 or more, with 

 their long, slender ostiola converging and erumpent through large, 

 subcircular openings 'in the epidermis, or irregularly scattered under 

 it, often in broad, continuous, or interrupted strips. The ostiola are 

 very brittle, variable in length, mostly not decumbent, and their tips 

 are not united in a disk. Asci abundant, 25-30 /j. long*(including the 

 slender base), and about 5 /x thick, clavate and rounded above. Par- 

 aphyses lanceolate, stout, much longer than the asci. Sporidia allan- 

 toid, nearly straight, hyaline, 5-6 x 1 p.. 



On bark of oak logs and limbs, Newfield, N. J. 



CaL assecla, (Schw.) 



Sphceria assecla, Schw. Syn. N. Am. 1622. 



Very minute, brown. Perithecia globose, collected in extensive 

 groups sometimes for half an inch around the pustules of other 

 Sphcerias, but seldom circinate. Ostiola three times as long as the 

 diameter of the perithecia, inclined, terete, comparatively stout. 



Under the epidermis of Castanea always associated with or sur- 

 rounding the pustules of other Sphcerias, Pennsylvania (Schw.). 



Cooke in his Synopsis 1901, places this in his subgenus Calo- 

 sphceria. The species is not represented in Herb. Schw. The de- 

 scription applies very well to C. pulchelloidea, C. & E., which may 

 be the same thing. 



Cal. niicrotheca, (C. & E.) 



Spliceria nricrotheca, C. & E. Grev. V, p. 51, and VI, p. 14. 

 Calosphceria microtheca, Sacc. Syll. 398. 

 Exsicc. EH. N. A. F. 580. 



Perithecia subgregarious or scattered, small (J mm. or less), 

 globose, black, submembranaceous, covered by the epidermis at first, 

 but when this falls away they become superficial. In some cases they 

 appear to have been superficial from the first, as on wood of bleached 

 limbs; in this case the base of the perithecia is slightly sunk in the 

 wood. Ostiola variable, often short, reduced to a mere subulate point, 

 erect, or elongated (1 mm.) and decumbent, directed towards some 

 opening in the epidermis. Asci clavate, stipitate, 22-25 (p. sp. 15-18) 

 x6 // (25x10 p., Cke.), racemose-fasciculate, soon truncate above.
