Stroma at first covered by the epidermis, soon emergent, almost 

 superficial and free, convex, orbicular or oval, rarely of irregular 

 -Impe, sometimes broadly effused, black inside and outside, punctulate 

 from the slightly prominent ostiola, clothed at first with the rufo-ferru- 

 uincous conidial layer. Perithecia rather. large, ovate, black, loosely 

 included in closely packed cells in the stroma, something as in Dal- 

 d'niia concentrica. Asci cylindrical, briefly pedicellate, 100-115 x 

 10 fjL, with very long and stout paraphyses. Sporidia uniseriate, ellip- 

 tical, hyaline at first, soon opake, 12-15 x 7-9 p.. 



Common on dead trunks and limbs of various deciduous trees 

 around Newfield, N. J. Mostly confined to dead oak. 



The hymemuin in this species, as in Hypoxylon Petersii, B. & C., 

 is at first covered by a carnose-coriaceous membrane, which soon dis- 

 appears, except around the margin.

Hypoxylon glycyrrhiza, B. & C. Exot. Fungi, Schw. p. 285. 

 Nummularia glycyrrhiza, Sacc. Syll. 1541. Cke. $>yn. 822. 



Suborbicular, thin (about 1 mm.), 3-5 cm. diam., convex, marked 

 in the center by the papillifbrm ostiola which are depressed in the 

 center. Perithecia oblong, | mm. in height, crowded. Asci (p. sp.) 

 40 x 5 p.. 



On bark, Ohio (Morgan, No. 284). 



Differs from N. Bulliardi, which it resembles, in its closely 

 packed perithccia and umbilicate ostiola, as well as in its smaller spo- 

 ridia. The Ohio specimen agrees with one in Herb. Schw. 



X. obularia, (Fr.) 



Hypoxylon obularium, Fr. Nova Symb. p. 130, 

 Nummularia obularia, Sacc. Syll. 1540. 



Immersed, erumpent, at length broadly effused, determinate, not 

 polished, stroma black, perithecia immersed, oblong. Ostiola hemi- 

 spheric-subprominent, umbilicate. 



On dead trunks, Costa Rica (Oersted). 



Closely allied to N. Bulliardi, Tul., but differs in having its 

 -troma connate with the matrix and inseparable from it, at first sub- 

 rotund, then concrescent in a continuous crust, generally elongated,
