Been awhile…

since I collected/photographed this. There are two photos here showing what appears to be a marginal area (>50%) exhibiting much paler color than is seen on the disc. Perhaps ambient lighting and/or the predisposition of my camera played a role.

I’ll explore the particular location/habitat again this coming summer.

Still puzzling on this one for which we only got nrITS.

Any thoughts about the cap coloration?

Sorry for the gap in the information. I mis-labeled the data and just discovered …

… the error. This material is definitely in sect. Vaginatae. In fact, it is very close to Amanita longicuneus on which I have been working for quite a few days. The pale zone on the cap (that is not so evident in the button, but seems to be there in a more distant shot of an adult) is kind of a surprise for longicuneus. Can you shed any light on the pigmentation? The somewhat olive tint is also a surprise.

Very best,

Rod

I had thought that that might be the case. :)

This is another cool one.

Very best,

Based upon my description of the habitat…

and my own record for location (edited the location for this observation) I believe I know the exact spot where these were found.

It appears this is something new.

I’m taking a fast pass through nearly 150 raw data files that came in in the last few days from Linas.

Very best,

Rod

I’m looking forward to the news from the sequencing.

Thanks again, David.

I just reviewed…

a couple of provisional species with globose spores found locally. A. cyclops looks somewhat similar, but with deeper marginal striations, a more prominently umbonate disc, and color scheme tending more toward brown than olive. Nothing else comes immediately to mind.
Sampled for DNA sequencing today.

Thanks as always, David.

Want to make a guess?

Very best,
