pora. Winter (Die Pilze, II, p. 547) is of the opinion that M. gigas- 

 pora, Fckl., is only an immature state of M. inqui?ians, (Tode).

Sporidia very large, 90-120x30 //, brown, 3-5-septate. 

 On bark, New York State (Gerard). Specimen too imperfect for 

 a full description.

surrounded by a hyaline stratum.

Perithecia scattered or subgregarious, globose, | mm. diam., cori- 

 aceous, raising the epidermis into pustules which are blackened and 

 pierced by the papilliform ostiola. Asci cylindrical, 150x12-15 if., 

 paraphysate. Sporidia uniseriate, oblong-elliptical, uniseptate and 

 constricted, hyaline at first with a gelatinous border, becoming dark 

 brown, 15-20 x 8-10 p. 



On outer 'bark of living Quercus alba, New York, New Jersey. 

 New England and Canada. 



The asci and sporidia in the American specc. {M. atrogrisea, 

 C. & P.) are constantly smaller than in the European specc, which 

 have asci 150-200 x 15-20 /*, sporidia 25-30x12-15 p, but there is 

 no other difference.

Sphceria Tilicz, Curr. Linn. Trans. XXII, tab. 59, fig. 104. 

 Massariella Curreyi, Sacc. Syll. 2709. 



Perithecia scattered, covered, \-\ mm. diam., black, globulose. 

 the papilliform ostiolum scarcely perforating the epidermis. Asci 

 broad-clavate, 80-90x25 ju, paraphysate, 8-spored. Sporidia aubbi- 

 seriate, obclavate, uniseptate-constricted, dark brown, upper cell 

 thicker, 35 x 12-14 p, with a gelatinous border. 



What appears to be this species has been found on Tilia, at West 

 Chester, Pa,, but the specc. are too imperfectly developed to be decided 

 with certaintv.
