for the detailed information. I would guess what I have here is similar to what Patrick has already sent you. We go to the same places in this area. I know Patrick and he has been a tremendous help to me with what I find. He has LOTS of experience compared with me. Whatever its name I enjoyed finding it. Good luck in your endeavors.

In the last year, I’ve been working with a group of people on the species people call “rubescens” in North America. We’ve made enough progress to see that there are a number of taxa that have been called rubescens. There are clearely more species than there are names. For this reason, I’ve created a lot of “temporary code” names so that we can put the information onto the WAO website as it becomes available.

At the moment, I think that youf images indicate that the species you have observed is NOT A. flavorubens or A. rubescens var. alba. Nor is it the European species, rubescens, which appears not to occur in North America. What it IS is, unfortunately, is another matter.

Patrick Harvey has contributed a number of rubescent collections to the above-mentioned study from your area (e.g., St. Louis and Ste. Genevieve Cos., Missouri). He has sent us both of the above species (excluded as possibilities); and he as sent us this additional taxon:


So, based on existing evidence, the latter species MIGHT be what you have collected.

Very best,
