A Disease of Currant Canes. 37 touching a flamed needle into a colony containing many conidia, and touching again to the stems. The only resulting growth, at first, was a thin, sparse mycelium, which was scarcely noticeable. No white cushions were produced. After about two weeks growth, in two of the cultures, minute red points appeared. When these had increased to the size of a pin-head minute red protrusions were pushed out from the summits of several of them. When examined under the microscope, each red point was found to be a stroma composed of compact hyphae, but bearing no conidia. The protru- sions presented every appearance of being forming perithecia. Unfortu- nately, the cultures were spoiled at this time, so that the resulting growth could not be l6. Mycelium of Pleouedria producing secondary conidia. Mycelium of Pleonectria was also innoculated to bean stems on which cultures of Tubercularia were growing, but the growth seemed to be in no way modified thereby. Innoculations. On May 4th, 1896, a series of innoculations of Nectria, Pleonectria and Tubercularia was made on currant cuttings. These were kept for a time in a forcing room in the conservatories, but were soon placed out-of-doors, after several of the plants had been attacked and killed by another fungus {Botrytis). About June 25th, several small, pink Tubercularia-\\" bodies appeared on two of the dead stems. These bore no conidia. Nothing has yet been produced on the living plants, nor, in the light of Mayr's experi- ments noted on a previous page, could results be expected in so short a Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York (State).
