This is especially the case in houses under glass, where the fungus, favoured by the moist atmosphere, lives as a saprophyte on dead plant-remains, and multiplies till it becomes strong enough to act as a parasite. It is, however, quite possible that conidial forms of other sclerotia { Scl. sclerotiorum) may be confounded with this Fig. liLSotrytis cinerea (Set. Fuckeliana). Branch of P}-unus triloba with two diseased shoots, withered and dead. (v. Tubeuf phot.) The presence of Botrytis and allied forms on the vine is the cause of a disease of great economic importance, because severe loss may be incurred through rotting of the grapes and the injurious after-effects on the "; A decay of the potato-plant is said to be caused by sclerotia formed inside the stems, and also by a Botrytis? Smith^ has figured similar sclerotia, which he ascribes to Peziza postuma Berk, and Wil. 1 H. M. Ward, Annals of Botany, 1888. ' Kissling, Hedwiyia, 1889. ^ 'Boa., Zeitsch. /.
