 forming small pustules ; sporidia biconical. — Curr. Linn. Trans.

On (twigs ?) Jan. Wey bridge. 



Sporidia biconical ; endochrorae grarmlar, or oleaginous, greenish ('0011-

Habitat and locality unknown.

 slightly acuminate at each end, uniseptate, greenish. — F. C. 



2493. Valsa furfuracea. Fr. " Branny Valsa," 



Irregularly circinating ; perithecia globose, mixed with yellow 

 branny dust ; ostiola very short, joined, obsoletely prominent ; 

 sporidia uniseriate, colourless. — S. furfuracea, Fr. S.M. ii. p. 

 409. Eng.Fl.^.p. 251. 



On branches. 



Perithecia about 12 together ; their ostiola minute, black, in a small flat 

 disc, which is not raised above the bark. Pustules on tbe same branch burst- 

 ing the bark transversely or longitudinally, sometimes three or four are con- 

 fluent, giving the plant altogether a different babit.^J/. /. B. 



2494. Valsa bitorulosa. B. ^ Br. " Constricted Valsa." 



Perithecia brownish, sub- pulverulent; necks decumbent, 

 straight ; ostiola confluent ; sporidia uniseptate, binucleate, con- 

 stricted at the septum and the articulations. — B. ^ Br. Ann.N.

On hornbeam. Dec. 



Concealed by the cuticle : perithecia globose, collapsed, circinating, about 

 eight in a group, with straight decumbent necks and confluent ostiola ; asci 

 clavate ; sporidia biseriate (■0007-'0008 in.) ■0177-'*J2 m.m. long, uniseptate, 

 constricted strongly at the septum and in the centre of each of the binucleate 

 articulations. Somewhat resembles the fruit of V.faginea, but is larger and 

 more constricted.— i>. ij Br.
