No color that I can find on the cap Dr. T.

The warts seem to be brown, tan and white. The veil has fallen away and is almost gone now. Unable to raise fibrils with fingernail. What scrapes off turn light brown or tan and same for fibrils seen with my loupe (10X). This specimen is available.

Were the warts originally a pale orangish white or pinkish white?

I think I see that in the first image.

If that is the case, try rubbing the stipe lightly with a clean thumb or finger and see if the fibrils you raise be come pinkish or orangish yellow.

If so, those are good characters for A. canescens.

Very best,


How about pigment development in the middle of the cap?

Is the partial veil very poorly connected to the stipe? Falling away?

This could be sect. Validae or sect. Lepidella. When I run into this delemna in southeastern U.S. material. I think of A. radiata/A. media in the Validae and A. canescens in sect. Lepidella.

Very best,
