 truding, usually broken off; sporidia colourless, elliptic-acumi- 

 nate, constricted in the middle, and irregular. — Curr. Linn.

Ostiola normally long and protruding, but mostly broken off j when the lon^ 

 ostiola are rubbed off" the plant looks just lilce I", quattrnata or V. turgiAa. 

 Sporidia biseriate ('OOOo in.) '0127 m.m. long.— i^.C.

CoxiDiA. — Tufts verrucajform, subglobose, aggregated, black ; 

 conidia obtuse, of the same colour. — Exosporium tilice, Lk. Obs.

AscoPHORE. — Perithecia deeply immersed in the inner bark ; 

 ostiola penetrating or concealed, surmounted by a circular greenish 

 disc ; asci stipitate, cylindrical ; sporidia uniseriate, oyate-ellip-

On lime twigs. 



Remarkable for the green disc above the perithecia. Mr. Currey's plant 

 does not appear to differ specifically from that of Tulasne. 



2497. Valsa crataegi. Curr. " Hawthorn Valsa." 



Perithecia irregularly globose ; ostiola rather short; sporidia 

 biseriate, oblong or elliptical, sometimes curved ; endochrome 4, 

 sometimes 2, partite, colourless, at length strongly constricted 

 and uniseptate. — Cu?t. Linn. Trans, xxii. p. 278, t. 48,/. 135 a.

On Hawthorn. 



Sporidia (-OOOe-'OOlO in.) •015--025 m.m. long. Of this species Messrs. 

 Berkelt^y and Broome observe that Mr. Currey's figure of the sporidia accords 

 with what they have seen in the eaily stage of growth, but at length they 

 are strongly constricted, uniseptate, with two distinct nuclei in each articu- 

 lation.
