Portion of leaf showing angular spots (nat. size). 
(b) Tuft of conidiophores emerging through a stoma (x 850). 
(c) Spores (x 850). 
Spots on the leaves, definite, more or less angular, limited by 
the veinlets of the leaf, 1-2 mm. in diameter, at first dark greyish- 
green, then brown; spots on the petiole, dark, much elongated 
up to 2 cm. long 2-3 mm. wide. Sori minute, crowded, 
chiefly on the under-surface, but also epiphyllous, white or very 
pale rose-tinted. Conidiophores fasciculate, emerging from the 
stomata, cylindrical, unbranched, finally more or less toothed 
towards the apex, 30-75 x 2-4-4 u. Conidia cylindrical, straight 
or very slightly curved, ends rounded, at length 1-septate, or 
rarely 2-septate, sometimes in short chains, 15-27 (9-35) x 3-5-4

Cercosporella Pastinacae, Karst. 
ew to Britain. Found on leaves and petioles and closely 
associated with Ramularia Pastinacae. Only a slight attempt 
_ was made to separate the two fungi in the field from which it 
appeared that the Cercosporella is by far the least common. 
When unmixed with Ramularia the spots are round (text figure 
2a), but as a rule the two fungi occurred together and their 
general distribution appears similar. 
With regard to the identity of the fungus there appears no 
doubt that it is the same as Karsten’s. Lindroth and Vestergren |
