H a b . Ou th e p u p a of some Hejiialus, Gunn.
The New Zealand species grows on the larva (not the pupa) of an iusect of the same genus. Ergot occurs on
Grasses in Tasmania, but it is uncertain to what species of Cordyceps it owes its origin.

Hypocrea is to Cordyceps what Hypoxylon is to Xylaria, containing those species whose stroma is horizontal,
and not essentially vertical. Theh bright colour at once distinguishes them, or, where that fails, the fleshy substance,
