f. 119.—On Elder, Fife House, Whitehall, January, 1866.—The spo- 
ridia are precisely those figured by Mr. Currey in Linn. Trans., cited 
above, under the name of Spheria syngenesia, Fr., and which he con- 
siders to belong to that speeies.— The specimen from which those 
sporidia were figured, was marked * S. Frangula, Pers. in litt," by 
Mougeot, in the Kew Herbarium, and this is identified with S. synge- 
nesia, by Fries in his *Elenchus' (ii. p. 78). Messrs. Berkeley and 
Broome, on the other hand, contend that another Spheria, called by 
them Valsa syngenesia, Fr., is the true Spheria syngenesia, Fr., accord- 
ing as it evidently does with the figure given in Fries's * Observations : 
(part ii. t. 7. f. 1). Hence we must conclude that Fries confounded 
íwo species, occurring on Elder, under the same name, through not. 
having regard to the fruit, which in Messrs. Berkeley and Broome’s 
species has minute sausage-shaped sporidia. I found during the past 
winter three distinct species of compound Spharia, on fallen twigs of 
Elder ; one of these corresponds with Messrs. Berkeley and Broome’s 
species, one with Mr. Currey’s species, and one to be hereafter re- 
ferred to. Undoubtedly the species with minute sausage-shaped spori- 
dia is a true Valsa; therefore the name adopted by Messrs. Berkeley 
and Broome is entitled to stand. The other appears to me, and also,
