prominent ostiola, clothed at first with the rufo-ferrugineous conidial 
layer. Perithecia rather large, ovate, black, loosely included in closely 
packed cells in the stroma, something as in Daldinia concentrica. Asci 
cylindrical, briefly pedicellate, 100-115 by 10//, with very long and stout 
parapliyses. Sporidia uniseriate, elliptical, hyaline at first, soon opaque, 
]2-15 by 7-9//. Thehymenium in this species, as in Hypoxylon Petersii 
B. & C., is at first covered by a carnosecoriaceous membrane, which 
soon disappears, except around the margin. Common on dead trunks 
and limbs of various deciduous trees around Xewfieid, X. J. Mostly 
confined to dead oak. Sec. Cooke in Grev. XII, p. 4, Sphceria clypeus , 
Scliw. is different, but Schw., in his Syn. X. Am., gives 8. clypeus as a 
syn. of 8. nummularia , and there is nothing in his herbarium at Phila¬ 
delphia to show that they are distinct.

Exot. Fungi Schw., p. 285. Suborbicular, margin thin, center snb- 
pulviuate, and marked with papilliform points (ostiola), which are de¬ 
pressed in the center. Perithecia oblong. On bark, Surinam, South 
America. Stroma pulvinate, 25 by 12 mm . Differs from N. Bulliardi , 
to which it is closely allied, in its oblong closely packed perithecia. 
The foregoing is the description of this species given in Sacc. 
Sylloge. We have seen no authentic specimen of this but one sent from 
Ohio (Morgan Xo. 284), supposed to be this, was submitted for determi¬ 
nation to Dr. Cooke, who was inclined to regard it as this species. In 
the Ohio specimen the perithecia are a little over one half millimeter 
long and are rather narrower than those of A. Bulliardi. The ostiola 
also are rather less prominent and are mostly slightly collapsed. The 
spordia are oblong, pale brown, 2-nucleate, 10-11 by 4-5//.

Symb., p. 130. “Immersum, erumpens, demurn late effusum, determina¬ 
tion, impolitum, stromate proprio atro, peritheciis immersis oblongis, 
ostiolis hemispherico-prominulis umbilicatis. Ad truncos arborum mor- 
tuos in Costa Rica, Oersted.” Closely allied to N. Bulliardi , Tub, but 
differs in having its stroma connate with the matrix and inseparable 
from it, at first subrotund, then concrescent in a continuous crust, gen¬ 
erally elongated; and ostiola depressed. The specimens examined by 
Fries were old and no trace of asci or sporidia remained. Cooke in Gre- 
villea places this species in the preceding section, but there is noth¬ 
ing in the description to show that the surface of the stroma is concave.
