I’m thinking at this stage of the game

we’re not getting more evidence than that to support a name! :)

Very nice!

Amanita texasorora !
Working on balancing the shading and daylight better. Maybe there is an argument for straight up flash shooting for consistency, even if the color is much too exaggerated in the results. I also always shoot in JPEG as I don’t have the software for dealing with RAW photos. I was thinking that it’s possible that having too much leeway in adjusting the photo would lend itself to exaggeration of color as well. My hope was to shoot at some easily replicated standard. But it’s not always possible in the field.

Is the natural light photograph extremely bleached. It is very gray for texasorora.

We have received DNA sequences for this material.

The collection representing this observation is accessioned as RET 715-7 in our herbarium.

We have received DNA data from this material. The nrLSU (Large Subunit) sequence is an exact match for Amanita texasorora. That is a 100% match against all but two of the texasorora sequences posted in GenBank.

The ITS sequence is of good quality. The genetic distance between the new sequence and those already deposited in GenBank ranges from 98.16 to 99.82 %. Since the ITS sequence of texasorora is variable, this is plausible.

Although the cap in the natural light seems very gray for texasorora, the molecular results suggest that texasorora is what we have in this case.

Very best,

Rod

Thank you, we’ll be glad to see it.
