On leaves of Viola paJiistris. 



Collected by D. A. Boyd on fading leaves of Viola 

 palustris at Ardrossan, Ayrshire Aug. 1916. The fungus 

 agrees wholly with that described by Diedicke though some 

 of the spores from the Ardrossan specimen are slightly 

 longer.

S. Oenanthis Ell & Ev. 



This species was previously found by D, A. Boyd on 

 Oenanthc leaves in Cumbrae and at Ardrossan (Trans, v. 

 p. 245, 1916). He now sends further specimens from West 

 Kilbride, which occurred in a damp wood on the stems of 

 the host, and which were causing the death of the plants. 

 In these stem pycnidia, the spores measure up to about 48/x 

 in length but do not otherwise differ from those on the 

 leaves.

" Perithecia irregularly seriate under the brown epidermis, 

 bursting in a w ide line ; spores large, ovoid, reticulately 

 cellular. 



On dead stems of Pteris aquilina, Bristol." 



This fungus has not again been recorded and the des- 

 cription is somewhat indefinite, but one found by D. A. 

 Boyd is evidently the same : — the pycnidia have a thin, dark 

 brown cellular wall and measure about 300/i across. The 

 spores on short colourless sporophores are as described by 

 Berkeley and Broome : they are divided by three stout 

 transverse septa and the compartments are irregularly 

 divided again by longitudinal and transverse delicate walls ; 

 they measure about 45/i x 20/x and become browner w'ith
