garis there occur near Aberdeen, in autumn, spots on the 

 leaves, in which I find an Ascochyta indistinguishable from 

 this, except that the conidia are 6-8 by i \-2. 



A. Primulse sp. n. 



Epiphyllous; spots like those of Phyllostida primulicola Desm. ; 

 pycnidia scattered over the spots, depressed -globose, pale 

 brown, diam. ioo-iio, papillate; sporidia hyaline, cylindrical, 

 obtuse, 5-6 by 2-2J. 



On Primula vulgaris, near Dunottar, in August. 



Ascochyta graminicola Sacc, 1, var. Brachypodii, var. 



nov. 

 Differs from the type and from Saccardo's varieties of the 

 species in the slightly curved and stouter sporidia, which 

 measure 15-17 by 5, and are slightly fusoid with blunt ends. 

 The pycnidia are not crowded, though arranged in groups. 

 On dead leaves of Braehy podium sylvaticum, on the roast 

 near Dunottar, in September. 

 2, var. leptospora, var. nov. 



Agrees with var. Hold Sacc. in the form of the sporidia ; but 

 the latter are rather smaller (12-14 by 2 2~3)j ano ^ are hyaline, 

 without guttse. 



On dying leaves of Agropyrum repens, near Old Aberdeen, 

 in September, and of Psamma arenaria on sand dunes 

 near Aberdeen, in August. 



Stagonospora aquatica Sacc. var. sex-septata var. 



nov. 

 This may be a new species, but it agrees so well with S. aquatica 

 in all respects except the slightly larger pycnidia (150 diam.), 

 and in the sporidia, which are slightly more slender (measur- 

 ing 32-35 by 5-6, instead of 26-28 by 5I), and have six septa 

 instead of three, that it seems better meanwhile to regard it 

 . as a variety of Saccardo's species. The slightly inequilateral 

 form of the sporidia is seen in this as well as in the type ; and 

 they live on the same host-plant. 



In dead stems of Scirpus lacustris, in the Corbie Loch, a 

 few miles from Aberdeen, in September. 



Stagonospora equisetina sp. n. 



Pycnidia innate, scattered, globose, diam. 80, brown ; sporidia 

 straight, fusoideo-cylindrical, 18-24 by 4-5, subacute, 6-8- 

 guttulate, faintly 5-7-septate, hyaline.
