There are any number of books on fungi, the ones shown here are a good selection and you could do far worse than these. There are also a number of guides that are truly, unbelievably awful, with poor drawings or photographs, useless descriptions and even potentially dangerous distinction.
In common with his other photographic guides, the Roger Phillips book on mushrooms is a stunner. I have been on many a fungus foray and this book has proved invaluable when identifying them at home.
There are over three thousand larger fungi to be found in the British Isles but it is impossible to find all, many are extremely rare. For example Phillips includes a photograph of Lentaria delicata, that had not been collected since first described in 1821. He also found a small mushroom near Wisley that proved to be new to science and was named in his honour. There is an updated edition from Phillips but I don’t see the need to replace the one I have.
The New Guide to Mushrooms is another photographic guide but less formal in layout. It also includes a number of ‘in habitat’ photographs. Less species are included but they are the most likely to be encountered. With the other information included, it makes a pretty good, one stop shop. though it is certainly not the ‘Ultimate’ guide it is purported to be in its title.
If you want a traditional field guide, with drawings, that is pocket sized, then the two volume set in the Penguin Nature Guides series is fine. I reckon the drawings are better than those in the Collins field guide that was released some thirty five years later! Originally published in Sweden (in Swedish) by Wahlström & Widstrand in 1977, they were translated and republished a year later by Penguin.
There is great fun to be had with fungi. While they may be encountered throughout the year, they are especially prevalent in the autumn, when less flowers are to be seen, so do much to restore interest in the forest floor.
It is some years since I last upended a fungi to make a spore print at home, but enjoyed those times immensely. I now content myself with the odd encounter with their various forms, striking colours and wild shapes as I pass them on my path.
