I’m excited to see what comes of this research!

AJ

We should add that…

the material will be scheduled for sampling for DNA sequencing.

This specimen has been received and accessioned into Rod’s herbarium.
Thanks,

Yep, 150F is high.

I try to use the medium setting or just above that on my dryer…which I think is in the range of 100F or a little higher. It’s a compromise because I need the gills to dry fast, but don’t want to screw up the DNA. There was one year at a foray when the temperature in the mycologists work area was 104F all the time. The dryers had to be hotter than the ambient temperature. I’ll tell you I was not sure of the state of my own DNA after three days of that.

Very best,

Rod

Thanks Rod

Unfortunately, I recently learned that temperatures over 100 degrees F can damage DNA. I dried this at around 150 degrees F, not realizing that it may interfere with genetic testing. I’ll make sure to keep this in mind for future collections.

Hello, AJ.

The material was received in good order. Thank you very much.

It seems to have dried fairly well. Wrapping a specimen in paper towels or toilet paper may slight rehydrate it because paper is very good at absorbing moisture from the air. This is why I have been working to eliminate cardboard boxes in my herbarium.

The mushroom looks in good order to me, but the absence of orange felted material on the stem makes me question the accuracy of jacksonii as a diagnosis. We’ll send a sample from the material to Santiago Sanchez to see what the genes say. They may have something to say even if the material is to you to have produced spores.

Very best,

Rod

You’re quite welcome

I’ll have it out tomorrow.

AJ

Thank you, j7u.

Great. Send the material to me at this address:

Again, thanks very much for your efforts.

Very best,

Rod

I’d be happy

to send this collection for study, just let me know where it should go.

Because of tje orange-fibrillose-felted material on the underside of the partial veil,

I’m inclined to place this mushroom in A, jacksonii.

Nice photographs.

Would you be willing to send part or all of your collection to us for study?

Please let me know.

Very best,

Rod

Thanks Eva

I imagine we are hunting very similar habitats! Greetings from the south shore of Lake Erie. I forgot to mention that it was growing under a small maple tree.

cool
