These conidioid forms were at first described as a separate species under the name of botrytis Jonesii.
Species of Mucor, botrytis, and other fungi, may also be met with.
The botrytis infestans, "attacks the leaves and stems of potatoes."
Snowdrops are sometimes attacked with a kind of mildew known scientifically as botrytis galanthina.
They were covered with mould, consisting chiefly of a species of Mucor, and one also of botrytis or Botryosporium.
The final or culminating cause of the disease known as the "potato-rot" is botrytis (peronospora) infestans.
