BOTRYTIS, a minute fungus which appears as a brownish-grey mould on decaying vegetation or on damaged fruits. Under a hand-lens it is seen to consist of tiny, upright, brown stalks which are branched at the tips, each branchlet being crowned with a naked head of pale-coloured spores. It is a very common fungus, growing everywhere in the open or in greenhouses, and can be found at almost any season. It has also a bad record as a plant disease. If it once gains entrance into one of the higher plants, it spreads rapidly, killing the tissues and reducing them to a rotten condition. Seedling pines, lilies and many other cultivated plants are subject to attack by Botrytis. Some of the species exist in two other growth-forms, so different in appearance from the Botrytis that they have been regarded as distinct plants:—a sclerotium, which is a hard compact mass of fungal filaments, or mycelium, that can retain its vitality for a considerable time in a resting condition; and a stalked Peziza, I in 1856. In 1861 and 1862 he conducted at Palermo, supervising or cup-fungus, which grows out of the sclerotium. The latter the production of his opera Marion Delorme in 1862, and in 1863 is the perfect form of fruit. The Botrytis mould is known as the conidial form
