the Genus Cordyceps. 1 1 
head, while at the apex they are short and unbranched, 
bearing a single head at the apex, but this is probably only 
due to their being younger, the development of the branches 
being acropetal. The branches consist of very slender hyphae 
running parallel to the long axis of growth, and expanding 
like a brush to form the apical head, each hypha bearing 
a chain of conidia at its tip, the terminal ones becoming free. 
So far as I can ascertain from the material at hand, the 
perithecia follow the conidial development on the same head, 
but on this point I am not certain. 
Ceylon (Thwaites, no. 1120 with sketch). 
Thwaites’ note accompanying the specimens runs as follows. 
£ Peradeniya, Dec. 1868. Parasitic upon the larvae of a lamel- 
licorn insect (one of the Melolonthidae), which feeds upon the 
young roots of coffee and other plants. No. 1120. Please 
call this Cordiceps Barnesii , B. and Br., after my friend E. H. 
Barnes, Esq., who first directed my attention to it.’ 
The specimen from Ceylon, £ on larvae of some lamellicorn 
insect at the roots of coffee-trees, Bolagodde,’ (Thwaites), and 
referred by Berkeley to Cor dy ceps sobolifera , Fungi of Ceylon, 
no. 978, proves to be Cordyceps Barnesii \ hence there is no 
proof of the extension of C. sobolifera from its Western home 
to Ceylon.
