Puffing is due probably to stimulus given^ to the protoplasm in contact with the ascus lid, ar it is observed when poisonous substances are applied such as iodin mercuric chloride, silver nitrate, copper sulphate, sulphuric and acet acids are used. With'some of these forms the ascus may be considers as a squirting apparatus by which a jet of spores leaves its mout The writer' noted the puffing of the spores in Peziza badia when tl large saucer-shaped fruit bodies were held in the hand.
