40-50 x 10-12 //, ciavate. substipitate. Bporidia subbisfcriate, allan- 

 toid, slightly curved, yellowish-hyaline, 12-15x 3|-4 /;.. 



On branches of Lignsti'mn. Bethlehem. Pa., and on dead limbs of 

 Clethra alni folia. Newfield, X. J. 



We have seen no specc. of Sphceria ligustrirva, Schw., but from 

 the diagnosis given by Schweinitz there can not be much doubt that it 

 belongs here. The specc. of Vaha obtecta, C. & E., have been care- 

 fully compared with V. Cypri, Tul.. as represented in Rehm's Asc 

 226, and seem to us to be the same. We find the ostiola united in a 

 disk, but there is on the same specimen a Valsa similar in outward 

 appearance, with the ostiola separate, Sphcvria pruinosct. Fr, S. M 

 II. p. 486, is reckoned as the sperniogonial stage, 



V. Ceanothi, (Schw,) 



Sphceria Ceanothi, Schw. Syn. N. Am. 1376. 



Subpustulate, closely covered by the epidermis, only the promi- 

 nent, black, round, shining, perforated ostiola visible. Perithecia sub- 

 erect, circmate in a cortical stroma, pyriform or irregular, white inside 

 Pustules minute, \\ lines diam. Sporidia (sec. Stevenson 1. c.) allan- 

 toid, nucleated, 21 J x 6.^ /*. 



Frequent on dead stems of Ceanothus, Bethlehem, Pa. (Schw.). 



V. mesoleiica, B. & C. Grev. IV. p. 103. 



" Disk white, surrounded by the black ostiola, or sometimes dotted 

 Sporidia hyaline, sausage-shaped, 20 // long." 



On Viburnum dentatiuii, Pennsylvania (Michener). 



V. inclinis, Sacc. Syll. I, p. 137. 



Valsa accltnis, Fr. in Cooke's Valsei of the U. S. p. 116, 



Perithecia circinate, about 5 together, globose, erect. Ostiola 

 parallel, crowded, thickened, prominent. Sporidia collected in tin 1 

 upper part of the asci, allantoid, 20-25 p. long. 



On branches of Sassafras, Bethlehem, Pa. (Schw,). 



The Valsa acdinis, Fr., of the European mycologists has sporidhi 

 only 7-9 x 2 /j. (Sacc.), or 12-14 p. long (De Xot), and must be different 

 from the V. acdinis, of Cooke's Valsei of the U. S 



Species imperfectly known. 

 \. laurina, C. & E. Grev. VII, p. 9. 



Covered by the blackened epidermis, Pustules convex. Ostiola 

 convergent. Asci ciavate. Sporidia cylindrical, slightly curved, ob- 

 tuse, hyaline, 20 x 4 /*. 



On twigs of Sassafras, New Jersey.
