One of the best pocket guides

This "Marcel Bon", well known mycologists, and mycophiles mycophagous, remains a benchmark, reliable although incomplete, since only contains 1500 species. However, the drawings are accurate and can be more faithful than even photography very successful.
I would not recommend to a beginner: the approach of names is in Latin, the structure is intended encyclopedic but not playful. Better to already have a solid knowledge of nomenclature before you can be comfortable in the field, in the use of this guide.
About me, I like its small footprint, and I tamed since 1988 that I own it.
