Alan, did she mean it is common everywhere,

including N. America? I sure would love to come across that pore surface on the F. gilva I find so often.

Must just be a variation which is more common then not. It’s good to have all examples of growth.

Who is working on this group. She said it is common for them to look like this, and it is F. gilva in her opinion.

It probably is a subspecies or variety

I have generated hundreds of sequences and none of the other ones got mixed up for any reason.

Like it could be a subspecies or variety. A lot of stuff on genbank is hit or miss and it may be time to pull out the scope and compare a few samples from different regions.

Thanks for taking time, Alan, to explain all

the possibilities for me. Such an intriguing mystery and certainly worthy of further investigation. I look forward to learning what you discover this summer about your fascinating specimens. Thanks again!

What does it mean?

Maybe this species is more variable than thought….Or maybe two closely related species have the same ITS sequence. Neither of those things are very likely. Maybe I switched the samples accidentally, or made a typo or pipetting error. Those two things are more likely. I have the dried collection, and will photograph and scope it when I see it – and verify the numbers written on the bag match the tube #‘s with the frozen DNA. I can also verify that the spores in the frozen DNA match the dried material, so I know that I didn’t put the wrong mushroom into the wrong tube at the beginning of the DNA sequencing process. Careful study of more samples from this location will be interesting – I’ll be back there this summer.

Alan, such an interesting Ob. Permit me please

an earnest question, and keep in mind I know very little about DNA sequences. How can this be a match for F. gilvus and have a maze-like fertile surface … so different from the tiny, round pores we are used to seeing on this species? Is this a new variant? I am so curious as to what this means.

It looks slightly different.
