Reddit reviews A Field Guide to Southern Mushrooms

I would not recommend the Audubon guide it is very out of date (this can range from outdated taxonomy all the way to toxicology that has changed over the years). It is useful because it lists species other guides lacks but you'll learn to hate it.

Buy a location specific guide. It depends on where you live. If you get really into field hunting buy some specific guides that give you a more in depth understanding and help you not to die. Joining a local mycological society is also an extremely valuable resource in understanding mycology.

The fifth kingdom beginner book, I would recommend this. It goes over fungal taxonomy Oomycota, Zygomycota and Eumycota. It also has ecology and fungi as food.

The kingdom fungi coffee table book it has general taxonomy of the kingdom but also very nice pictures.

Introduction to fungi Depends on your definition of beginner, this is bio and orgo heavy. Remember the fungi you see pop out of the ground (ascos and basidios) are only a tiny fraction of the kingdom.

NAMA affiliated clubs

NC rank amatuer here - When I was just getting into it, a couple of mycologists recommended two guides: A Field Guide to Southern Mushrooms and the 1991 ed of Mushrooms of North America by Roger Phillips, which I believe has been superseeded by this book. Alas, the local mushroom club disbanded and the experts moved away before I gained confidence in self-identifying and eating more than canterelles, morels, hen-of-the-woods, sulfur shelf and oyster. And since then, our favorite morel grounds has become a series of soccer fields. But, I still find oysters with some regularity on river walks where I know the terrain and the downed trees. That may be way too basic for you, but do check out FG to Southern Mushrooms.
