Spharia (Circumscripta) fulvo-pruinata, Berk. — On dead Platanus 

 oceidentalis. Cincinnati, January 14, 1842. 



Pustulata, subangulata, basi effusa, peritheciis oblongis, collo elon- 

 gato; stromate discoque ostiolis punctata fulvis; sporidiis ellipticis, 

 uniseptatis. — Berk, in Hook. Lond. Journ., vol. iv., p. 312. 



Forming somewhat angular pustules, about a line broad, rather 

 effused at the base, as seen through the thin cuticle; disc angular, 

 tawny, pulverulent, pierced by the black punctiform ostiola; stroma 

 tawny like the disc: perithecia globose; asci linear; sporidia elliptic, 

 uniseptate, with a single globose nucleus in each cell. 



Spharia ( Circumscripta) Leaiana, Berk. — On bark of dead Horn- 

 beam. Cincinnati, June 20, 1839. 



Innata; stromate pallido, laxo, e cortice et ligno linea circumscripta; 

 peritheciis ellipticis, ostiolis subconfertis, elongatis, lineolatis, granu- 

 latis, sporidiis minimis curvulis. — Berk, in Hook. Lond. Journ., vol. 

 iv., p. 311. 



Ab<mt half a line in diameter. Perithecia not numerous, circinate, 

 elliptic, seated on a pale stroma of rather a loose texture ; ostiola form- 

 ing a little tuft rather elongated, umbilicate, finel}' grooved, granulated: 

 asci lanceolate; sporidia minute, curved like those of S. verruciformis. 

 Distinguished from S. carpini b} r its pretty, granulated ostiola; but 

 above all by its minute, curved, not lanceolate sporidia. In S. dicipiens 

 the sporidia are dark and elliptic with one side flattened. 



Spharia (Coxfluextes) rhizogena, Berk. — On the roots of Gledits- 

 chia triacanthos, washed bare by the Ohio freshets. Cincinnati, Dae., 

 1840. 



Suborbicularis, atro-fusca; stromate pallido, peritheciis globosis, 

 primum cervino-pruinosis, demum supra atro-fuscis, subtus pallido- 

 fuscis; papilla subtili abrupta quandoque depressa, intus pallido-fuscis. 

 — Berk, in Hook. Lond. Journ., vol. iv., p. 312. 



Patches nearly orbicular, two lines or more broad, with their surface 

 rather irregular, here and there depressed; stroma pale, 3-ellowish- 

 brown ; perithecia minute, dull, not shining, partially immersed, pale 

 brown when shaded from the light, nearly black above, at first pruinose, 

 globose'with a minute and sometimes depressed papilla, filled with pale 

 brownish jelly; asci linear, sporidia, elliptic. Habit that of S. labiwni. 

 Its nearest all} r appears to be S. yleditschice. S. meloyramma as pub- 

 lished by Mouegeot differs in its fusiform sporidia. Fries, No. 441 has 

 curved sporidia.
