From Science Daily: DNA samples from fungi collections provide key to mushroom ‘tree of life’.

Genetic material from fungi collections at Purdue University and the Royal Botanic Gardens, Kew, helped a team of researchers resolve the mushroom “tree of life,” a map of the relationships between key mushroom species and their evolutionary history that scientists have struggled to piece together for more than 200 years.

I guess that means all of my mushroom identification books will be outdated in a few years. But that’s ok. Better to know a thing than not to know a thing, for the most part.
