Glad the book worked for you, Dave. At the NEMF foray last year I was able to confidently ID a yellow russula I dug up from the display table. In most cases, however, the book leads to a dead end or a very tenuous ID. Still, it’s better to have it and use it that just giving up on russulas altogether.

Which letter did the spore print color correspond to in the book color chart?

I’ll give it a try.

Given it a yellow russula, you should be able to key it out with Kibby & Fatto book.
