Pycnidia gregarious, occupying long stretches of the twigs, covered, 

 at length bursting the epidermis at the summit, depressed-globose, 

 thick-walled, 60-70 yu diam. ; texture ver}'^ dark brown, with an indis- 

 tinct pore. Spores shortly cjdindric or oblong, with rounded ends, 

 scarcely or not constricted, brown, 8-10 X 3|-4| jj.

Pycnidia round or oblong, convex, up to 400 /x diam., black, 

 covered, then bursting the epidermis, surrounded b}^ a brownish stain ; 

 texture very soft and yellowish -brown, composed of small cells. 

 Spores oval or elliptic-oblong, acute at base, more obtuse above, pale 

 yellowish-brown, very translucent, with one, then often two, more 

 rarel}^ three septa, 10-13 X 4 ^ ; sporophores linear, filiform, persis- 

 tent, 10-15 X 1 /J. 



On twigs of Cornus alba. Kilwinning, Ayrshire (Boyd). Dec. 



Distinguished by its pale colour and long slender sporophores. 

 The 2-septate spores Avere very common ; in them the loculi were 

 sometimes equal, but usually one septum was median, and the other 

 at the lower quarter length. Hendersonias like vagans should form 

 a distinct section of the genus.

Pycnidia up to \ mm. diam., rather crowded, black, very convex, 

 roundish or elongated, covered by the epidermis, then bursting it 

 irregularly or by a slit ; texture thick, dark, indistinct, paler inwards. 

 Spores oblong, rounded at both ends, often slightly curved, 3-septate, 

 not or hardly constricted, with frequently one or two longitudinal 

 divisions, 15-18 X 7-8 /x, cells uniformly brown, the central cells 

 often shorter than the terminal ones ; sporophores short and in- 

 distinct. 



On cone-scales of Plcea excel sa. Hereford. May. 



The spores were of all sizes and colours, from small hyaline ones, 

 exactly like those of Phoma strohiligena Desm., through 1-septateor 

 brownish up to those of 2i Hendersonia, one or two of the central cells 

 tinally becoming divided by a longitudinal septum.
