Diseases of plants induced by Diseases of plants induced by cryptogamic parasites; introduction to the study of pathogenic Fungi, slime-Fungi, bacteria, & Algae diseasesofplants00tube Year: 1897 400 URKDINEAE. characteristic of G. clucariacformc. No mycelium occurred in the wood. A comparison of normal bast with that of infected twigs revealed clianges similar to those already described for G. davariavformc. In addition, it is to be noted that the thickened bast-fibres no longer occurred in closed masses, but were often completely absent in the first year after infection, while in all diseased twigs every intermediate stage exists between thin-walled bast-elements and thick-walled bast-fibres, such as never occur in the normal twigs; in fact, many twigs had thin-walled elements only.
