fusoid-falcate. 6. Vermicularia. 



A. A. Pycnidia caespitose, immersed in, or adnate to, the stroma. 



H. Sporidia ovoid-oblong ; stroma globoso-truncate, incom-

 irregularly plurilocular. 8. Cytospora. 



H.H.H. Sporidia rod-like, usually straight, stroma conico-trun- 

 cate, carbonaceous, typically plurilocular. 9. CeutJwspora. 



L. PHYLLOSTICTA, Pers. 



Pycnidia usually subcutaneous, membranous, thin, pore fre- 

 quently wide ; sporidia small, ellipsoid or ovoid, hyaline or 

 yellowish ; basidia very short or absent. {Note. The fungi referred 

 to this genus often appear on spots previously overgrown by 

 Ramularia, and allied genera, among Hyphomycetes, and are 

 succeeded on some plants by such forms Ascochyta and Septoria 

 among Sphceropsidece. It is more than likely that these genera 

 represent forms of reproduction of Sphaerella and allied genera 

 among Pyrenomycetes.)

 Spots dry, circular, except where broken by the leaf-margin, 

 pale in the middle, with a darker border ; pycnidia numer- 

 ous, lenticular ; sporidia very small, 3-4 by 1-1 \. (In this 

 Journal in January, p. 40, I recorded this as P. hedericola 

 D. and M. ; but the form found near Aberdeen proves to be 

 P. Hedera S. and R.)
