IN NATURE, vol. ix. p. 161, it is stated by Mr. W. G. Smith that the bodies referred by Dr. Montague to Artotrogus are possibly no other than Volutella ciliata. Nothing can be more common on decaying potatoes than V. ciliata, but I can state most positively that Montague's fungus, whatever its nature may really be, had nothing to do with V. ciliata. It is very important that attention should not be drawn off from Dr. Montague's, or rather Dr. Rayer's curious observation by a supposition which is entirely without foundation. A reference to the figures in the Journal of the Horticultural Society (vol. i. tab. 4, figs. 27, 28, 29), and the characters of Artotrogus, apart from the specimens submitted to myself, and the occurrence within the cellular tissue, ought to be quite sufficient.
