MYCOLOGICAL NOTES 45 



strongly echinulate yellow spore. There are about 20-25 in each 

 fascicle. The spores are echinulate all over ; the character which 

 was at first given to the genus, of having one side of the uredo- 

 spore smooth, is now known to be not of universal application. 



Hemileia Phaji Syd. a, tuft of spores, emerging from a stoma, x 150 ; 

 b, young spore ; c, mature spore, x 500. 



On comparison with the figure of Uredo Lynchii, given by 

 W. G. Smith in Gard. Chron. 1885, p. 693, f. 154, it will be seen 

 that the spores of that species form pustules which burst the 

 epidermis and belong to some quite different genus, at present 

 unknown. 



Puccinia Zopfii Winter. This species on Caltha pahistris 

 bears a close outward resemblance to P. Caltha, but is distin- 

 guished essentially by its teleutospores, which are provided with 

 a few, rather distant, minute warts, mostly towards the upper 

 end and rather difficult to see. Moreover, the spores are 

 relatively much broader, more oblong, and not narrowed towards 

 the summit; they are therefore easily seen to be distinct in shape, 

 and have a darker colour and shorter pedicels. Both species have 

 aecidia on the Caltha in May, but it is not known how these 

 differ, if at all. I first detected this Pucci?iia on specimens sent 

 me from Ireland by Mr. J. Adams, but on examination of others 

 preserved in herbaria it is found to have occurred in Wales, 

 Scotland, Shropshire, Yorkshire, and elsewhere; Mr. J. Barns- 

 bottom has kindly examined the specimens in the Herbarium 

 of the British Museum for me. 



Ascochyta Beassic^: Thum. — This and the two following 

 species were also sent by Mr. J. Adams. 



Pycnidia epiphyllous, small, black, prominent, very densely 

 crowded on pale whitish-grey spots, which are roundish, oblong, 

 or irregular, and 12-25 cm. in diameter; sporules fusiform, acute 

 at both ends, straight, uniseptate, 15 x 3 [x.

Darluca genistalis Sacc. Pycnidia about 80/* diam., black, 

 ovate, slightly and obtusely papillate, collected into little dense, 

 tubercular, subhemispherical, erumpent clusters; sporules fusiform, 

 straight, rather obtuse, uniseptate, colourless, 12-15 x 2| p. 



On sori of Uromyces Anthyllidis, Co. Dublin, September, 1906. 



Texture of pycnidia parenchymatous, pale grey below, becom- 

 ing dark brown, but still translucent towards the apex ; sporules 

 without any visible terminal appendages. 



Synchytrium Succis^ De By. et Woron. Galls hypophyllous 

 or a few epiphyllous and on the petioles, brownish-black, minute,
