On branches of beech. [Mid. Carolina.] 



The branches on which it grows, and which it generally surrounds, are of 

 a bright red-brown. The perithecia vary in size an din the number grouped 

 together, which is from 3-8, their ostiola collected in an erumpent brown 

 disc. Sporidia (-OOOS-'OOOi in.) -OO/e-'Ol m.m. 



2505. Valsa convergens. Fr. " Convergent Valsa." 



Perithecia about six together, minute, ovate, circinating, con- 

 verging, as well as the round, somewhat attenuated, erumpent 

 ostiola; sporidia dark brown, subcymbiform, irregular, frequently 

 constricted. — Fr. S.V.S. p. 411. Curr. Linn. I'rans. xxii. t. 48,

On smooth bark (Platanus occidentalis). 



The perithecia are under the bark so as not to be seen above, except by the 

 undulations of the bark. — F, C. 



2506. Valsa pasrmulairia. Berk. " Triangular Valsa." 



Small, pustulieform ; perithecia circinating, laterally com- 

 pressed ; ostiola scarcely distinct, umbonate ; asci linear ; spo- 

 ridia broadly oblong, uniseptate, brown. — Berk. Hook. Journ, no. 

 308. Curr. Linn. Trans, xxii. it. 48,/. 163. 



On oak. King's Cliffe. 



Scarcely a line broad, forming little pustules with a black umbo ; peri- 

 thecia circinating, closely packed, so as to present, when cut through, a tri- 

 angle with one curved and two straight sides ; ostiola in general indistinct j 

 asci linear, containing 8 brown broadly oblong uniseptate sporidia, like 

 those of many DqAodice. 



This curious species has been known to me for some years, but has never 

 been published in consequence of the doubt attached to its position, because 

 of its growing on living bark Externally it is not unlike Sph. turgida. The 

 perithecia vary from o-lO, always laterally compressed, so that a section re- 

 minds one of the carpels of an orange. — M.J.B.
