Diplodina Ammophilse. Perithecia scattered in the spaces 

 between the nerves, oval, opening by a slightly papillate ostiolum 

 on back of leaf, dark ; spores hyalines broadly fusiform, 30 by 12^., 

 uniseptate (cells very distinctly outlined), each end of the spore 

 bears a short mucoid appendage as in Darluca. On the Links 

 near Aberdeen, in dead leaves of Ammophila arundinacea. 



The spores would rather indicate Darluca as the genus for this 

 fungus ; but it has immersed perithecia, and is not parasitic, 

 though, indeed, this latter character is not found in all the species 

 of Darluca. 



Hendersonia Equiseti. Perithecia subdermal with a small 

 ostiolum, nearly spherical, about 180^. in diameter; spores pale 

 brown, fusiform, or nearly cylindrical, with rather obtuse ends, 12 

 to 20 by 2 to 3^., 3-septate. 



In dead stems of Equisetum (? limosum) near Aberdeen. The 

 perithecia resemble those of Siih&ropsis epitricha B. and Br., 

 which also is found in Equisetum stems, but the latter species has 

 simple spores. 



Stagonospora Heleocharidis. Perithecia scattered, subder- 

 mal, with a small ostiolum, nearly spherical, 130 to 170^. in 

 diameter, spores pale yellowish, fusiform, 30 to 40 by 6 to 7^., 

 5-7-septate. In dead leaves and stems of Heleocharis palustris in 

 the neighbourhood of Aberdeen ; common. 



Stagonospora paludosa S. and Sp. (Sacc. 2475). A fungus 

 that agrees pretty well with Saccardo's description is common in 

 dead leaves of Carex ampullacea near Aberdeen. My specimens 

 may be described as follows : — 



Perithecia scattered, subdermal, but nearly free from surround- 

 ing tissues, with small ostiolum, about 220^. in diameter; spores 

 pale yellowish, fusiform, 42 to 52 by 8^. 7-9-septate. 



Doubtless numerous other Sphaeropsideae will be met with in 

 Scotland when carefully sought for ; but of greater importance 

 than adding to their number is the determination of their relation 

 to the more matured forms of fungi.
