377. (conidiferous). — Libertella faginea, Desm. I. c.f. 5. (spori- 

 diferous). 



On trunks of beech-trees. Common. — In an imperfect state it is a 

 mere gelatinous mass of minute globose conidia ; the perfect sporidia

On elm-leaves. Common. — My reasons for following Desmazieres 

 in placing Septoria in the present situation have been stated in a former

 Septoria, as the former appellation has been used for a genus of Gas- 

 teropodous Mollusca. 



2. S. OxyacdnthcB, Kunze. (Hawthorn Septoria) ; spots pur- 

 ple, tendrils yellow, sporidia very long 8 — 12-septate curved.
