Phoma stagonosporoides sp.n. 



In dead leaves of Phragmites communis on shore of Loch 

 Achray. Pycnidia innate, scattered, depresso-globose, 

 with papillate ostiole, thin, 120-150 diam.: sporules ellipti- 

 cal, 10-12 by 3-4, hyaline, faintly 4-guttulate. From the 

 description of Stagonospora hysterioides (Karst.) Sacc. the 

 sporules appear to be very similar to those of that plant ; 

 but the pycnidia of the latter are too different ("gregariis, 

 erumpentibus, elongatis, hysteriiformibus, usque ad • 1 

 mm. longis ") to permit of specific identity. Both would 

 appear to fall under Phoma more naturally than under 

 Stagonospora, though approaching that genus in the pluri- 

 guttulate sporules. The same appears to hold with regard 

 to Stagonospora Luzulw (West) Sacc, which, to judge by 

 the description of it in the Sylloge, must greatly resemble 

 Phoma stagonosporoides in its sporules. 



? Cy tospora Dubyi Sacc. 



On dead needles and twigs of Juniperus commujiis, in the 

 Trossachs. What appears to be this fungus was plentiful 

 on dead needles still hanging on the bushes (less so on the 

 twigs themselves), but I do not feel confident in the identi- 

 fication, which I rather suggest for confirmation or cor- 

 rection. Saccardo regards G. Dubyi as the spermogonium 

 of Valsa Dubyi Nit, not yet recorded as British. 



Ooniothyrium Scirpi sp.n. 



On dead culms of Scirpus (Heleocharis) palustris on shore of 

 Loch Achray. Pycnidia scattered, innate, thin, brown, 

 spherical, diameter about 100-150. Sporules broadly fusi- 

 form, 9-10 by 4-5, pale brown. 



Ascochyta decipiens sp.n. 



On the same culms as Coniothyrium Scirpi. Pycnidia innate, 

 depressed, spherical, about 120 in diameter, thin, dark 

 brown. Sporules abundant, elliptical, not constricted, 9-1 1 

 by 2J-3J, hyaline, with a very delicate median septum. 

 This is a true Ascochyta, and seems distinct from any 

 described form, though without any very well-marked charac- 

 teristic features.
