 pom. Fckl., is only an immature state of M. uni_ninan&, (Tode). 



M. Gerardi, Cke. (pro tern.) Grev, VIII, p. 118. 



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

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

 a full description. 



MASSARIELLA, Speg. 



Fungi Arg. Pug. I, p. 2. 



Perithecia and asci as in MaSsaria. Sporidia uniseptate, brown, 

 surrounded by a hyaline stratum.

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

 aceous, raising the epidermis into pustules which are blackened and 

 pic-reed by the papilliform ostiola. Asci cylindrical, 150x12-15 //. 

 paraphysate. Sporidia uniseriate, oblong-elliptical, uniseptate and 

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

 brown, 1 5-20 x 8-10 //. 



On outer bark of living Quercus alba, Xew 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 25-30 x 12-15 /* r but there is 

 no other difference. .

Sphcsria Tilics, 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, 80-90 x 25 //, paraphysate, 8-spored. Sporidia subbi- 

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

 thicker, 35 x 12-14 //.. 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 certainty.
