The mode in which the germ-tubes attack the host-plant is very remarkable. Woronin says: ' The germ-tubes developed from the ascospores grow inwards towards the vascular bundles of the host-plant and enter them; then they continue to develop, but n

The striking belief that it is a herb insummer and a worm in winter, may perhaps sufficiently account for theesteem in which it was held. Tin ascospores are multicellular and filiform and when shed break upinto their separate cells. Germ-tubes from these, or from the conidia, infectthe insect either as a caterpillar or chrysalis, and penetrating into its interiorgive rise to cylindrical conidia which enter the blood-stream and increaseby east-like budding till the insect die
