50 l'AUKIN : FUNGI PARASITIC 



The conidia are of the Fusariurn type (fig. 06). The 

 number of their Bepta were observed to vary from 3 to 9. 

 On the whole i hoy are somewhat more curved than the 



aidia of Nectria coccidophthora. The hyphse bearing them 

 are filiform and only branch at the base. 



Tin' Oylon forms so far collected may be divided into 

 three types ; whether of specific value, it is difficult to say. 



(a) On Aspidiotus aurantii and Mylilaspis citricola (fig. 62). 



- oma not conspicuously developed; sporodochia arranged 

 in stellate fashion around the scale, as many as eight, 

 cushion-shaped or conical, projecting outwards horizontally 

 or slightly inclined upwards: its sheath may extend for 600/'. 

 while the conidial part only projects 370/<, breadth varies 

 from 337-525/* (fig. 63). Oonidia, average size 103*8 x 4'6/< 

 with several septa. 



(b) On Aonidia bullata and A. crenulata (i\g. 64). 



Stroma well developed, broad border 133-1 60/« wide ; Bpo- 

 rodochium only one (or at most two) to a scale, springing 

 from the posterior end of the insect as a horizontal or 

 obliquely inclined conical structure with its bright pink tip 

 usually just visible amid the jairged fringe of the sheath, 

 measuring L50-300 x 180m (fig. 6">). Conidium 80-S8 x 

 '5m. 



The position of the Bporodochium is probably accounted 

 for by the structure of the insect. hi tin 1 genus Aonidia 



the scale is dosed below, so the anal and genital apertures 

 would afford tlir easiest exit 1 for the funen .

(c) On Aspidiotus camellia (?) on the bark of a jungle treei 



31 'oma oonspicuous ; sporodochia oolumnar or somewhat 



club-shaped, projecting vertically upwards around the 



e, measuring 600 x 1*0/*. The sheath, white or buff in 



colour conidia, usual ourved septate type 80 x s /( . 



On one piece <»f bark around some of the scales pink 



i of the Seotria or Sphssrostilbe type were situated,
