but Gyfospora Lauri, on Laurus nobilis, is not. The two species 

 are, as might be expected, quite different in structure. 



880. Cytospoka subclypeata Sacc. in Malpigh. 1896, x. 273, 

 pi. 6. f. 1 ; Sjll. xiv. 917. 



Stromata scattered, pustular, |-| mm. diam., swollen, covered by 

 the shining black epidermis, gre}^ within and unequally plurilocellate ; 

 disc minute, grey. Spores sausage-shaped, curved, 4-5 X 1 /x ; sporo- 

 phores verticillately branched, 25 X 1 /a, branches acute.

 Ayrshire (Boyd). May- Nov. 



In these specimens the epidermis over the pustules is dark reddish- 

 brown, shining especially at the apex when young ; many of the 

 sporophores are rather fasciculate at the base than branched ; spore- 

 mass colourless, spores 3-6 X |-1 n.

S))ots smooth, shining, inky-black, with a paler radiating margin. 

 Pvcnidia occu])ying the centre of the spots, more or less convex or 

 conical, somewhat prominent, mouthless, black.

The spots on these specimens are for the most part oval, about 

 5-8 mm. long ; the pycnidia are ver}^ black, some few containing 

 oval continuous spores, measuring 7-8 X 2|-3 fu. With them was to 

 be found an immature P3n-enomycete.

 1896, p. 142. Sacc. Syll. xiv. 924. Allesch. vii. 36. 



Pvcnidia rather large (150-250 /^ diam.), oblong, obtuse, covered, 

 at length erumpent by the vertex. Spores oblong, obtuse, yellowish- 

 brown, with one large guttule or 2-5 smaller ones, 8-10 X 4-5 fx.

333. CoNiOTHYRiUM GLOMERULATUM Sacc. Syll. iii. 314. 

 Allesch. vii. 23. 



Pycnidia aggregated (2-5 together), immersed, then erumpent, 

 subglobose, black, about. 150 /a diam. ; texture of minute cells, very 

 thick and dark. Spores copious, oval, 3-4 X 1^-2 /x, olivaceous- 

 brown ; sporo])ho]'es not seen.

334. AscocHYTA CAEPATHiCA Grove, f. caulicola. 



No spots. P3^cnidia scattered, lens-shaped, dej^ressed, brownish, 

 covered, then erumpent by the vertex, which is pierced by a minute 

 pore ; texture parenchymatous, thin, translucent, pale-brown. Sj^ores 

 at first ovoid, 1-celled, then oblong and 1-septate, rounded at the 

 apex, 7-9 X 2i-3 /u. (Fig. 12.)

As the spores become 1-septate, they usually become a little longer 

 and a little narrower. But both kinds can be found continually
