Var. minor Sacc. Fung. Veu. ii. 322 (1875) ; Syll. Fuug. iii. 437 

 (1884). 



Perithecia minute, globoso-papillate, black, innato-crumpout ; 

 sporules cylindrical, somewhat curved, 25 /a x 3 /*, 8-septate, 

 yellow. (Sacc. I. c). 



On the dead culms of a small grass ( ? Poa), near Three Shire 

 Oak (St.), April, May. Spores cylindrical or subfusoid, 20-2G// x 

 3^/x, pale yellowish. Distinguished from 11. f/raminicola hov. by 

 its more slender and paler spores. 



52. Stagonospora pini, sp. n. — S. peritheciis epiphyllis, 

 tectis, sparsis, rotundatis, atris ; sporulis pallide luteolis, singulis 

 liyalinis, cyliudraceo-fusoideis, utrinque subobtusis, 1- dein 3-sep- 

 tatis, 16-20 M- X 3-4 fx,.

subrotund ; perithecia 1-3, epiphyllous, brown-black, very minute, 

 opening by a pore ; sporules very long, curved or flexuose, multi-

 Aug. With Phyllosticta cytisi and Leptosphairia Lucina. 



54. Septoria dianthi Desm. Sacc. Syll. Fung. iii. 516. 



This I had previously (Jouru. Bot. May, 1884) considered as 

 recorded in ' Grevillea,' v. 70; but having by the kindness of 

 Mr. C. J. Muller seen the specimens (Cooke, exs. i. 429) there 

 referred to, I find them to be widely distinct. They are on 

 Saponaria, and may be either Septoria dimera Sacc. or a species of 

 Ascochyta.
