“This is essentially a new book in the same broad subject area … and they have been thoroughly revised and have different authorships. … I have concentrated here on chapters which I found of particular interest myself … . The Editors are to be congratulated on putting such a great selection of topics together!” (Hawksworth, IMA Fungus, February 5, 2024)“The fourth edition has swelled by a rather modest 126 pages, but what really makes it stand out is that many of the photographs of Petri-dish cultures are now in colour—a most useful addition. ... The book will … remain as a treasured testimony to the work of a most remarkable man who devoted most of his life to improving our understanding of food spoilage issues involving fungi, and particularly the characterization of the species involved.” (IMA Fungus, Issue 2, February 5, 2024)
