By W. B. Groye, M.A. 



Part VI., of which this is a continuation, ajipeared in the Journal 

 of Botany in October-December, 1918. Mr. D. A. Boyd continues 

 to furnish a number of highly intei'esting new discoveries from the 

 rich part of Scotland in which he lives. 



C(EL0MYCETES. 



304 Phyllosticta anceps Sacc. Syll. iii. 39. Allesch. vi. 132- 

 f . NoxiosA f . nov. 



Spots small, scattered, roundish, pale ochraceous-yellow (not 

 greenish at first), visible on both sides of the leaf, 1-2 mm. across, 

 but the leaf -tissue round the spots becomes of a bright yellow to 

 a considerable distance. Pycnidia amphigenous, frequently circinate, 

 black, globose-lens-shaped, 70-80 /x- diam., pierced by a pore or faintly 

 papillate ; texture truly FJij/llosticta-like, thinly parenchymatous, 

 slio-htly darker round the pore. Spores oblong or ellipsoid, rounded 

 at^both ends, often slightly curved, mostly with a rather large guttule 

 at each end, 4-5 x 1^-2 /a. 



On young radical leaves (and especially the leaf-bases) of J^as- 

 titrtmm aniphihium, on the banks of the river Cole, Yardley Wood, 

 April. 



The spots are most abundant on the narrowed leaf -bases, crowded 

 and killing the tissues over a wide and conspicuous bright yellow area. 

 On the lamina the spots are more distinct, fewer and bordered by a 

 narrow brown line, each enclosing a few pycnidia. Many of the 

 lower leaves were all but destroyed. 



305. Phyllosticta Asperul^ comb. nov. 



Depazea Asj^erulce Lasch. Sacc. Syll. iii. 63 ; non Phyllosticta 

 Asperulis Sacc. & Pautr. Syll. xvi. 810. 



Pycnidia hypophyllous, round, globose-lens-shaped, 60-75^ diam., 

 black, immersed, at length somewhat superdcial, opening by a centiul 

 pore; texture brownish, plectench3'matous, darker round the pore.- 

 Spores oblong, biguttulate, 3-4 X |-1 /x ; no sporophores. 



On fading or dead leaves of Asperula odorata. Dahy, Ayrshire 

 (Boyd). Jan. 



Pycnidia on irregular spots which are indistinct, withered and 

 pale, but not bleached white. Most of the pycnidia were immature 

 and contained no spores ; see Klotsch, Herb. Myc. no. 1867. The 

 spores were found in pycnidia on the dead leaflets. 



306. Phyllosticta Briardi Sacc. Syll. x. 109. Allesch. vi. iSQ. 

 P. mail Briard, Suppl. p. 79 {non Prill. & Delacr.). 



Spots very various in form, visible alike on both sides of the leaf, 

 brown or subochraceous, with a similar but darker (or even purpliL>ih) 

 border, chiefly marginal or apical, up to 2 cm. across. Pycnidia 

 epiphyllous, scattered, punctiform, immersed, black, 80-100 yu diam.,
