EDIBLE FUNGI

SIR,—Anent the interesting piece on mushrooms by Leslie Adrian, your readers may be interested in Christensen's Common Edible Mushrooms (Univer- sity of Minnesota Press, Minneapolis, Minn., 1943). It devotes one section to 'The Foolproof Four'—four kinds of edible mushroom with characteristics which positively distinguish them. The final section of this book is entitled `Mushroom Cookery.'
