On decaying leaves of Oxycoccus (Vaccinium) palustris, Taser- 

 miut, Greenland, on green leaves of Oxycoccus macrocarpus, Penn- 

 sylvania (Schweinitz). 



In the Greenland specc. the asci are narrowed a.bove from a 

 broad base, 85-95 x 20-25 fx. Sporidia ovoid-oblong, uniseptate and 

 constricted, at first hyaline, then olivaceous, 24^32x8-10 fi. 



V. compacta, Pk. 25th Rep. p. 106. 



Perithecia minute, (200-230 fi), subglobose with a papilliform 

 ostiolum, collected in dense clusters or groups, 15-30 together, on the 

 lower side of the leaves, thickly covered with short, spine-like,' black 

 bristles 25—40x3-4 (i. A.sci fasciculate, clavate-cylindrical, about 

 40 X 6 /z, with abundant paraphyses more or less branched. Sporidia 

 obliquely uniseriate or subbiseriate above, oblong-ovate, subolivaceous, 

 12-15 [1 long. 



On living leaves of Vaccinium macrocarpon, New York (Peck), 

 northern New Jersey (Halsted). 



Specimens from Maine have the perithecia less compactly grouped; 

 mostly in small, orbicular patches margined by a circle of perithecia, 

 as in V. orbicula.

On orbicular, dark brown, \ mm. spots, which are mostly of a 

 lighter color (gray) in the center. Perithecia scattered, orbicular 

 (75 //), membranaceous and rather coarsely cellular, with a few black, 

 continuous, straight, spreading, 35x3 ;/ bristles above. Asci ovate- 

 oblong, 30-35 X 8-1 1 fi, broader and slightly curved below, sessile, 

 without paraphyses. Sporidia biseriate, subhyaline (with a greenish- 

 yellow tint), ovate-oblong, 3-4-nucleate, uniseptate and slightly con-

 lous, erumpent, becoming superficial, seatied on a filamentose subiculum, 

 subspherical, black, clothed above with spine-like bristles 40-80 jx long.
