Very best,

So do you want these washed out amerirubescens? See obs 171336.

We have two collections of rubescens var. alba from Maine; however, neither of them was posted on MO. One is from Bill Bakaitis (Lincoln Co.) and one, from Linas Kudzma (York Co.). The “sp-amerirubescens02” collection is indeed the one you mention in your comment. The other collection is not yet confirmed as “ap-amerirubescens07” by sequencing; so it is not in my count.

Very best,

Rod

Looks like I’ve made another late night mistake.

We haven’t found the A. rubescens var. alba

as far as I know, although we thought we might have in the same area as this posting see obs 140265. Of the samples we sent you one was determined to be A. sp-amerirubescens02”, obs 140446. I recently sent you a sample of what might be sp amerirubescens07, obs 141052. Mostly we find the pink fleshed cap variety in vast quantities. I see them in the same places year after year and in all their stages of growth and under various growing conditions. These were after heavy rains as were those in obs 140458. I don’t document them every time we see them but some other obs are 141055, 140263, 139432. If you’d like I’ll dry a specimen for you when next we find one after rain.

In the tentative listing of rubescent taxa in North America,

there were two of your collections from Maine that appeared. One was rubescens var. alba and the other was “sp-amerirubescens02”…if I remember correctly.

It is possible that this material represents the first of these. It would be interesting to see if your area is producing just these two “rubescent amanitas” or if there are other genetically separable taxa present.

White caps can be found (sometimes) in some of the rubescent taxa other than rubescens var. alba. As you know, we are still gathering data.

Very best,

Rod
