This glossary of technical and scientific terms used in the world of the growers of edible fungi is the considerably enlarged successor of ‘Mushroom terms in five languages’, a publication which was out of print for more than 10 years. To the original five languages English, German. Dutch, Danish and French, two more have been added, viz. Italian and Spanish. The main table of the glossary consists of 1169 numbered English terms in alphabetical order, each followed by the corresponding terms in the other six languages. Additional alphabetical indices in these other languages refer to the numbers of the terms in the main table.
