\ mould referable to this genus was found by the author 

 in the Royal Botanic Gardens, Peradeniya, Ceylon, on the 

 scale. Asterolecanium miliaris, which was infesting the 

 leaves of a bamboo bush. A curious point, about the position 

 of the fungus was its restriction to those scales fixed to the 

 low or side of the leaves, while those on the upper surface 

 were attacked by ;t species of Nectria already described (see 



p. 24). 



The Verticillium covered the scale with a gray mycelium, 

 which extended as well some distance around over the leaf 

 surface. The scale together with the fungus could easily 

 be detached with a needle from the leaf and mounted on a 

 slide for examination. Through the microscope numerous 

 conidiophores could be seen standing erect from the 

 mycelium. Each is composed of a stalk bearing at the top 

 a single whorl of 5-9 short pointed branches, sterigmata, 

 bearing solitary conidia (fig. 55). The stalk measured 

 38-41 x 'Aft. the sterigma 8-11// in length, and the conidium 

 4 x 1*4/*. The latter is slightly curved, in fact sausage- 

 shaped. 



Thus the Ceylon specimen has an unbranched conidio- 

 phore with one whorl of sterigmata, whereas the genus is 

 usually characterized by possessing several superposed or 

 alternate whorls of sterigmata. V. heterocladwn, already 

 alluded to, has a compound conidiophore with verticillate 

 branches ; so the Ceylon specimen is quite different from it.
