Sphj5ria (Cihcumscript^) fulvo-pruinata: pustulata, subangulata, 

 basi efFusa, peritheciis oblongis, collo elongato; stromate discoque ostiolis 

 punctato fulvis; sporidiis ellipticis, uniseptatis. Berk, in Hook. Lond. Jaurn., 



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, rniisejitate, with 

 a single globose nucleus in each cell. 



' Sphjeria (Circumscripta) Leaiana: innata ; stromate pallido, laxo, e 

 cortice et ligno linea circumscripto ; peritheciis ellipticis, ostiolis subconfertis, 

 elongatis, lineolatis, granulatis, sporidiis minimis curvulis. Berk. inHook. Lond. 

 Journ., vol. iv. p. 311. About half a line in diameter. Peridiecia not nu- 

 merous, circinate, elliptic, seated on a pale stroma of rather a loose texture ; 

 ostiola forming a little tuft rather elongated, umbilicate, finely grooved, granu- 

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



Distinguished from Sp. Carpini by its pretty, granulated ostiola ; but 



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

 sporidia are dark and elliptic with one side flattened. 



3 SpHiBRiA (CoNFLUENTEs) RHIZOGENA: suborbicularis, atro-fusca stro- 

 mate 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, yellowish-brown ; perithecia minute, dull, 

 not shining, partially immersed, [)ale-brown when shaded from the light, 

 nearly black above, at first pruinose, globose wida a minute and sometimes 

 depressed papilla, filled with pale brownish jelly; asci linear, sporidia ellip- 

 tic. Habit that of S. Laburni. Its nearest ally appears to be S. Gleditschia. 



S. melogramma as published by Mougeot differs in its fusiform sporidia. Fries 

 No. 441 has curved sporidia.
