I just blasted that sequence and I also got R. pectinatoides (along with R. amoenolens and Gymnomyces fallaxBUT
My hit to pectinatoides had a max identity of 95%, and an E value of 0.00… not bad for 642 bp…
What makes you say it’s pretty far off? I know how to use the tools, but not necessarily how to interpret them.

Thanks Darv

So the closest match in genbank is Russula pectinatoides, but even that is pretty far off… There is a single (distant) match for Macowanites ammophilus, but the ITS is only 91% identical.

Duh. Right when I hit the create button. Sorry.

Any odor?

At least some of the Macowanites can be separated by smell alone.

This collection was half buried showing only the top of the cap. The grass covered the top and made it almost impossible to see unless you stood directly above it. It was taken fresh to UC Davis for DNA work.

Macowanites I find in Santa Cruz are aboveground.

Found mostly hypogeous?

Another characteristic for Macowanites, as it no longer needs much stipe. Or is this in the transitional phase between Russula and Macowanites? I do wish someone would sort this bunch out.
