When this was first brought to the attention of the Gardener's Monthly, now many years ago, we expressed the opinion that it was of fungoid origin. Of course we had to make the guess from analogy, as it requires great knowledge and skill in microscopical studies to be able to work these matters up positively. Mr. Worthington G. Smith has recently done this, and finds it is a fungus - a new one - and he names it Urocystis Gladioli.
