Tay (St. Cyrus, near Montrose). 

 Causing black patches on the stems, in which are grouped small 

 black sub-globose pycnidia, under the blackened epiderm, 

 aperture almost or altogether absent j sporidia oblong, 

 straight, 3-5 by 1^-2, Hyaline. Saccardo suggests that 

 P. melcena is probably the spermogonium of Sphcerella 

 melcsna (Pr.) Awd. ; but I found no trace of the Sphcerella 

 on the stems. 

 *27. P. superflua, Sacc, 826, C. 139, S.M. 3033. (D. and R. 

 Trail, Sc. Nat. 1885, p. 128.)

 Dee. 

 *28. P. macrocapsa, Trail, S.M. 3077. (D. and R. Trail, Sc. 

 Nat.., 1 386, p. 327.) 

 On dead stems of Mercur talis perennis, near Aberdeen.

 *29. P. saligna, Fr. (D. and R. Trail, Sc. Nat., 1887, p. 90.) 

 On dead leaves of Salix cinerea, with Linocera Capraia? (of

 *3o. P. deusta, Fuckel, 925. (D. and R. Trail, Sc. Nat., 1887, 

 p. 90.) 

 Causing dark patches on the stems and fruits of Rhinan- 

 thus crista-galli on the Links, near Aberdeen. 

 Dee. 

 Pycnidia beneath the dark epiderm, sub-gregarious, papillate, 

 prominent: sporidia 8-10 by i-|-2, sub-cylindrical, straight, 

 hyaline ; basidia simple. 



c. On Fruits and Flowers of Dicotyledons. 



*3i. P. leguminum, West, 870, C. 141. (D. and R. Trail, not 



previously recorded.) 

 On dead pods of Cytisus Laburnum, near Aberdeen. 

 Dee. 

 Pycnidia small, scattered in large groups, spherical, dark; sporidia 

 oblong-ovoid, obtuse, 5-7 by 2 J, hyaline, biguttulate ; 

 basidia very short. This fungus comes very close to, if 

 it is not identical with P. herbarum.
