That’s very useful. I appreciate the effort.

Very best,

Habitat:

The exact location where I found these specimens is an upland site dominated by large-sized white oaks (Quercus alba) with an understory of Ostrya virginica. There are sundry other tree species in the area, including Liriodendron tulipifera, Quercus rubra, Q. falcata, and Carya spp. Very few Pinus taeda, mostly died out now. I’d call it mixed hardwoods dominated by oaks. GPS: 33°59’21" N 83°29’43" W

I want to be sure I understand the sort of woods in which this materila was found. Is it entirely comprised of oak trees (mixed species)? Or is it mixed hardwoods dominated by oak? Or is it mixed conifers and hardwoods dominated by oak? I’m submitting the sequences to GenBank and would like to be as accurate as possible in describing the habitat.

Very best,

Rod

if you already have both examples in your hands, Rod

can’t you examine them for more similarities/differences other than DNA?

are you certain these two dissimilar grisettes are perfectly DNA matched? Isn’t getting these mushrooms to species w/just DNA “matches” a bit of a judgement call?

I do believe that they are related, which the DNA should clearly show.

Not surprising at all that we see similar species fruiting in different areas here on MO. It happens all the time in many different genera. It is these inquisitive, documentarian field collectors that are truly driving our knowledge base, and sharing their finds as well as spending a good bit of money, in some cases, to send these samples on to others.

Without a photo and a specimen, it’s just a rumor!

MO is a great resource for all. But I don’t envy you your attempts to tease out the grisettes of the world, Rod. Next step, finding ways that we can tell them one from another w/out needing a lab to do it.

Can you make it rain?

Then I’ll look for a younger specimen! (It’s been too dry for too long.)

Who would have thought that MO would provide both known collections of this…

critter?

Of course, it is a hypothesis that the two collections belong to one species. We have supporting evidence, of course, but more would be wonderful. Maybe, Bill, you can find a younger specimen in all its glory. :)

This kind of stuff is very rewarding. My gratitude to all involved in collection and discussion on MO.

Very best,

Rod

Thanks Rod!

The mushrooms pictured in the two obsies don’t look like the same species at all, even if one takes into account the difference in age.

The original (immature) MO obsevation of this species is…

Dried material resembling these images is desired for research purposes.
