The material has been received and will be scheduled for sampling for sequencing.

Very best,


Ah, thought it was found in this condition.

We have a reddening amanita, that a bit more conical than yours and somewhat darker that I’ve seen a couple of times, that I thought was a different species, maybe it’s not.

Thank you, Patrick.

I should be sending this out with a few more finds from the past week tomorrow

The present specimen would

represent an unsampled county. We could put it into the sampling schedule. Patrick would allow me to use the dried specimen?

Very best,

There are a very few scales on the cap. There was a thunderstorm the night before, so many of them had washed off.

La Barque Creek is in northeastern Jefferson county, south of Eureka, Missouri

the combination of cap surface gelatinization and the friable to pulverulent nature of the volva.

If this critter had not met its fate in Patrick’s dryer, I think there is a good chance that it would have expanded to fit the concept of amerirubescens a bit better than it might appear to do as immortalized in these photographs.

We are just starting into a geographically broad, genetic, preliminary investigation of the rubescent group. Our largest set of samples to date went off to the post office yesterday morning. This included a sample that I labeled “amerirubescens” from Jefferson Co., MO.

In which county is La Barque Creek?

Very best,


This is probably another species of red staining amanita,

It’s not robust enough, the unopened cap is conical instead of rounded and there’s no scales on the cap.
