04 PARKIN : FUNGI PARASITIC 



Cambridge, November, 1905. 



Postscript. — A new conidial form from Natal. 



While this paper was in preparation for the press, the wri- 

 ter received from the Government Entomologist of Natal a 

 fine specimen of a coccid-fungus distinct from any hitherto 

 examined. It is a conidial form attacking scales of MytiJas- 

 pis citricola on the stem of a Citrus (?), and was found in 

 Znluland in November, 1905. A cursory examination has 

 revealed the following features. Standing up around the 

 Bcale are a few whitish bodies, resembling somewhat in 

 general appearance the sporodochiaof Nectriacoccidophthora. 

 Each consists of a short stout brown stalk, surmounted by a 

 broad sub-conical white or cream-coloured head. An average 

 sized one gave the following measurements : — 



Stalk, length 05 mm., breadth 042 mm. 



Head, height 033 mm., width OG8 mm. 



The stalk is stroma-like in texture, its component parts 

 not separating in water. The head, on the other hand, swells 

 in water liberating conidia. In fact, it consists solely of a 

 mass of a conidia without any sheath or admixture of sterile 

 hyphffl ; neither are there any separate fertile hypha? bear- 

 ing the conidia. These, in fact, sit upon the broad top of the 

 stalk. They are borne in pairs— occasionally in threes— on 

 the tips of hyphffl which barely project above the general 

 level of the stalk-top. Thus the conidia may be regarded as 



ssile, the conidiophore being almost suppressed. 



The conidia are long and straight, multiseptate with their 

 free ends tapering. The longest measure about 150m x 8/*, 

 and have as many as 17-20 septa. 



The fungus dues not seem to fall readily into any of the
