184 FUNGOID PESTS OF CULTIVATED PLANTS. 



white or of a pale ochre, with a broad violet margin showing brown on 

 the under surface. The receptacles are scattered over the upper face of 

 the spots and enclose the very minute subglobose sporules (2-2 Jx 1J /x). 



This species was first detected in Portugal. 



Sacc. Syll. iii. 32. 



A black mould (Cercospora Myrti) has been detected upon leaves 

 under cultivation at Stockholm, but this seems to be the only record. 



PHILLYBEA LEAF-SPOT. 

 Phyllosticta Phillyrea (Sacc.), PL XVII. fig. 15. 



This spot is found on the leaves of Phillyrea media and Phillyrea 

 latifolia, affecting the upper surface, and producing variedly shaped spots, 

 of an ochraceous-grey colour, with a reddish margin. The receptacles are 

 scattered over the spots, and enclose the oblong, almost spindle-shaped 

 sporules (6-7 x 3 /x), each containing two minute guttules. 



It has been recorded in France and Italy, as well as Britain, and 

 should be treated as other leaf-spots. 



Sacc. Syll. iii. 113 ; Grevillea, xiii. 72. 



Another species is known in Portugal (Phyllosticta phillyrina), 

 occurring on leaves of Phillyrea obliqua, but with smaller sporules 

 (4-5x2-2^). 



PHILLYBEA BUST. 

 Uredo Phillyrea (Cooke), PI. XVII. fig. 16. 



This uredo is found sometimes rather plentifully on shrubs of 

 Phillyrea media, not only in Britain but also in Germany, Italy, and in 

 Algeria. The pustules are round, yellow, and either solitary or collected 

 together, arranged in rings. At first covered by the cuticle, but at length 

 exposed. Uredospores globose, pear-shaped, or elliptical, delicately 

 spinulose or almost smooth, orange (17-28 x 12-16 ft), without definite 

 pedicels, and with a thick hyaline outer coating. 



Sacc. Syll. vii. 3090 ; Plowr. Brit. Ured. 258. 



PHILLYBEA CLUSTEB-CUPS. 

 Mcidium Phillyre (DC). 



These cluster-cups, which appear to be independent of uredo or 

 teleutospore, occur on the leaves and twigs of Phillyrea media and 

 latifolia, sometimes contorting and deforming the latter. 



The cups are clustered in roundish patches on the leaves, for the most 

 part crowded, with the margins nearly entire. ^Ecidiospores very variable 

 in form, being sometimes globose, or elliptical, or pear-shaped (18-85 

 x 14-20 /A), externally warted, orange-yellow. On the stems the clusters 

 are more elongated, thickened, and distorted. 



Known in France, Germany, and Italy. 



Sacc. Syll. vii. 2852.
