CORDYCEPS MILITAIUS. 

 By G. T. Lyle.

It is well known that certain species of fungi are developed 

 on pupae, generally in the ground, but it would seem that the 

 occurrence of these fungi growing in captivity is somewhat 

 rare, so I was much surprised to find recently a well-developed 

 specimen attached to a silk and earth cocoon containing a dead 

 Geometrid pupa (probably Oporabia dilntata) in one of my glass- 

 topped metal boxes which contained a little mould. The speci- 

 men has been kindly identified for me by Mr. J. F. Rayner, of 

 Southampton, as Isaria farinosa, the conoidal state of Cordyceps 

 militaris. The colour was creamy white, texture mealy. The 

 photograph is twice natural size.
