On dead twigs of Scdix. Sutton Coldfield. Apr. 



On the same twigs was an abundance of Valsa germanica Nits., 

 of which it is the spermogone ; when the two occurred together, the 

 G-9 black ostioles of the Valsa formed a ring round the spermogone, 

 at a distance of |-1 mm. away from it. Occasionally the grey disc 

 of the Cytospora was pierced by two papillse. See below for the 

 Valsa. 



327. Cytospora Hyperici, sp. n.

No definite conceptacle. Pycnidia scattered, conico-truncate, 

 4-1 mm. diam., with a rather large whitish furfuraceous disc, dark 

 olive Avithin, composed (Avhen perfect) of many compait, narrow, 

 radiately arranged pseudolocelli or labyrinthiform chambers ; walls of 

 the locelli, under the microscope, thick and dark bi'own without a 

 trace of green. Spores sausage-shaped, curved in profile, 4-5 X |-1 />t, 

 rather more acute at the ends than is usual ; sporoj^hores linear, not 

 very crowded, + curved, 10-12 X 1 /-i. 



On dead twigs of Laurus nohilis. West Kilbride, Avrsliire 

 (Boyd). May. 



The confusion originated by Greville's mistake in calling our 

 " Common Laurel " Laurus nohilis, and perpetuated in Saccardo's 

 Sylloye, vol. iii., has never been completely dispersed. Ceutliospora 

 Laurocerasi (Fckl.)=:6\ JLauri Grev., on Prunus Laurocerasus, 

 is very common in Britain (see Journ. Bot. 1916, p. 1916, p. 191),
