B. Renouana Sacc. & llouiu. Syll, iii. GO. 



Spots amphigenous, at tirst oblong-lanceolate, 10-15 nun, long, 

 bright cinnamon-rust-coloured, becoming paler in the centre, after- 

 wards involving the whole of the leaf-tip. P3'cnidia occupying the 

 centre of the spots, afterwards scattered over the whole of the dead 

 area, minute, punctiform, 60-75 n diam., lens-shaped, black, at 

 length opening by a wide pore; texture parenchymatous, thin, some- 

 wdiat tawny. Spores ovoid or ellipsoid, hyaline, 4-5 X l|-2yL<. 



On the tips of the leaves of Ti/pha latifuUa. Kilwinning, Ayr- 

 shire (Boyd). July. 



The mycelium is at first trul}^ parasitic, forming numerous ochre- 

 ous spots, with a broad rusty border, towards the tip of the leaf, the 

 centre of each being occupied by the pycnidia ; but afterwards, as 

 the leaf dies, similar but more minute pycnidia are found over the 

 whole of the ochraceous dead area, arranged more or less in rows. 

 l^liyUosticta Renouana Sacc. & Ixoum, is evidently only one of the 

 stages of growth of P. typliina. 



816. Phoma endokkodia Sacc. Syll. iii. 124. AUesch. vi. 278. 

 Pycnidia gregarious, covered by the epidermis, globular, 200-250 /x 



diam., ostiole obtuse, piercing the epidermis ; contents rosy pink ; 

 texture thin, submembranaceous, distinctl}^ parenchA'matous, dingy 

 ochraceous, only faintlj^ darker round the ostiole. Spores oblong to 

 cylindrical, rounded at both ends, biguttulate, 8-9xl|-2ju (or 

 even 2| /x) 



On dead peduncles of Lapsana communis. Hopwood, Birming- 

 ham. April.

In this Journal, 1912, p. 50, I recorded what I considered to be 

 this species on twigs of Gooseberry. Then there was a slight doubt, 

 but in March, 1921, I found what is undoubtedly the true species on 

 twigs of Salix fraqilis at Quinton (Ws.). The species has been 

 recorded on Salix and Ribes before ; and also, abroad, on LaiiruSy 

 Fopiclus, Prunus, Quercus, Rosa, and Vitis. 



It is very remarkable for its peculiarly branched sporophores, on 

 the lateral teeth and short branches of which the spores are obliquely 

 seated, but the sporophores on Salix were much longer than those on 

 Rihcs.
