erally subseriate, (1 mm. diam.), -svhite inside, surrounded by the epi- 

 dermis. Peritliecia scarcely distinct (subconfluent), ratlier obtuse, 

 opake. Asci clavate, 8-spored. Sporidia elliptical, continuous, hyaline,

On bark of Aralia spinosa, Carolina (Curtis). 



B. Viburni, Oke. Grev. 1. c. 



Stromata erumpent, gregarious, very small (|-| mm.), corticolous, 

 depressed-pulvinate, dark brown, surface tuberculose, white inside. 

 Perithecia 6-10, subimmersed, convex above, perforated. Asci cla- 

 vate. Sporidia narrow-elliptical, continuous, turning yellow, granular, 

 18-21x8 II. 



On branches of Viburnum opulus, United States. 



Closely allied to B. Aralice, of which it may be a variety. 



B. Hypericornm, Cke. Grev. XIII, p. 102. 



Subelliptical, flattish, black. Perithecia small, connate, white 

 inside, closely embraced by the ruptured epidermis. Asci clavate, 

 8-spored. Sporidia narrow-elliptical, continuous, hyaline, about 20 x 

 5 n (immature). 



On stems q{ Hyfericum proliferuni, United States. 



B. stomatica, Scliw. Grev. 1. c. 



Widely effused, emergent, staining the wood black. Perithecia 

 semiimmersed, rather large. Ostiola large and ])rominent, cylindrical, 

 obtuse. Asci clavate, 8-spored. Sporidia elliptical, continuous, brown, 

 12-13x5 II. 



On rotten wood, Indiana. 



Differs from the others in its brown sporidia. 



We have seen no specc. of the last six species, and take the 

 descriptions from Gi-evillea. 



B. Arctostaphyli, (Plowr,) 



SphiEria Arctostaphyli^ Plowr. Grev. VII, p. 73. 

 Boiryosphtsria Arctostaphyli, Sacc. SyU. 1764, Cke. Syn. 1405. 



Perithecia superficial, depressed-globose, black, roughish, gre- 

 garious, i-1 mm. Ostiola obscurely papilliform. Asci clavate-pyri- 

 form, 70x15-20 //. Sporidia continuous, ovoid, sometimes a little 

 curved, 15-18x4-5 ^, hyaline. Spermogonial perithecia about the 

 same as the ascigerous ones. Spermatia oblong, hyaline, 5-7 x 2 ;/. 



On bleached wood of Arstostaphylns, California (Harkness). 



Our specc. from Dr. Harkness show only spermogonia. The 

 stroma seems to be entirely wanting.
