ovate-globose, mostly only partly sunk in the stroma. Asci cylindrical, 

 8-spored. Sporidia (typically) two-celled, the two cells which are gen- 

 erally spherical, soon separating so that the ascus appears to contain 

 16 sporidia.

Stromata gregarious, superficial, subhemispherical, elliptical, or 

 irregular in shape, mostly J-l cm. diam., convex when fresh, con- 

 tracted and rugose when dry, nearly brick-colored, punctulate from 

 the slightly projecting ostiola, whitish within. Asci cylindrical, nearly 

 sessile, 65-75x4-5 //, with 8 uniseriate, didymous sporidia, composed 

 of two subequal, hyaline, subglobose, or subcubical cells, each 3-4 // in 

 diam. 



On dead limbs of Andromeda ligustrina, Newfield, N. J., on de- 

 caying wood and on old Polyporus, Carolina (Ravenel), also on decay- 

 ing wood and bark from various localities. Probably found through- 

 out the U. S.

"Stromata gregarious, 2-3 lin., broad, thick, margin repand, disk 

 nearly plain, partially free from the matrix. Perithecia minute, glo- 

 bose; immersed, ostiola punctate, minute." 



The only specimen of this species in our possession was sent from 

 California by Dr. Harkness and is on wood of fir (Herb. Hark. 3496). 

 In this specimen the stromata. are \-\ cm. in diam., nearly round, 

 central portion adnate, leaving a narrow, free margin closely applied 

 to the surface of the wood. The pale, globose, carnose-membranaceous, 

 peripheric perithecia (200-220 fi in diam.) lie in a single layer, their 

 ostiola very prominent and distinctly roughening the surface of the 

 dirty-black stroma. Asci cylindrical, 80-100x5-6 //, without paraph- 

 yses, containing 8 two-celled sporidia, each cell subcubical, or nearly 

 globose and 4-4 J ti in diam. or slightly ovoid, 4-5 x3| jut.
