When “var. pallida” was removed from the suggested name, it was not removed from the title of the present page.

var. pallida as an abandoned distinction…

This variety of Amanita brunnescens has been abandoned. The history on this goes back to Dr. R. Pomerleau who first observed that he felt there was no taxonomic value to the name in one of his publications on the mushrooms of Quebec. I have found a fairy ring that included both brown and pallid caps of brunnescens.

[See www.amanitaceae.org/?Amanita+brunnescens .]

The remaining question of a pallid lookalike involves whether A. aestivalis should be considered to be the same as, or different from, A. brunnescens.

[See www.amanitaceae.org/?Amanita+aestivalis .]

In the case of a picture, the question (for those who remember the Johnny Carson Show) is “How pallid is it, Johnny?”

Here’s my suggestion: In Photoshop, use the automatic correction of contrast and color functions. Then desaturate the cyan and/or blue to remove the background color (it will only appear as a reflection on the mushroom and makes it harder to judge subtle colors on the mushroom).

Then judge apparent color and apparent speed of bruising…which are the two tools at hand for separating aestivalis and brunnescens.

Very best,

Rod
