Notes:
Found in same location as obs 204747 and obs 186636: roughly 10 m from a mature pecan and 30 m from a mature live oak. Each fb was buried relatively deep with upwards of a quarter of the stipe requiring excavation. Also worth noting: two of the fbs (the “fresher” ones) had what appears to be ephemeral pv material hanging from stipe. The volvae tend to adhere more to the surrounding dirt than to the stipe, making excavation difficult. One of the fbs (the upcurled, dessicated fella) has its volva intact.

I look forward to receiving the material.

In the current pictures, the darkish band near the inner end of the marginal striations is present in some specimens and not in others.

Very best,

Rod

I’d say that the colors are fairly accurate, and yes, it does seem as if the fbs fade from a richer brown-gray to a drabber gray over time. I’ll be on the lookout for more, and with some luck, I can better document the color variations.

I would add that now I’m second-guessing myself w/r/t the “UDF.” It may be a different species, as you note. When I send this material (along with some other stuff that I’ve been sitting on), I’ll be sure to separate them.

Logan, can you shed some light on the (apparent) variation in cap color.

It looks as though the immature material is very densely pigmented and that this changes significantly with maturity and exposure (to sun?). This would not be unusual in Amanita; however, we need to conifirm the material is all one species. One way to start this process is for you to indicate whether the images all show true color of what you believe is the same taxon? Have you watched one specimen go from the zonate cap with rich brown coloring to the less zonate caps with much “faded”(?) coloring?

This stuff is quite interesting. It’s very exciting to see what may be insinuans showing up again. And if there is more than one species with a weak annulus near your pecan tree, that is also cool.

Very best,

Rod

Very interesting, Logan.

I’d like to see the material.

I wonder if the “upturned, dessicated fella” (“UDF”) is the same species as the others. It strikes me that it might be different.

I’d like to see all the material if that is possible. Please package the “UDF” separately from the rest of the material.

Very best,

Rod

huh.

vaginatae with annuli, caesarea w/out, what is this world coming to?

nice documentation, Logan.
