Used references: Arora’s Mushrooms Demystified, p. 279 under Amanita porphyria, described as “very common (mainly under hardwoods) and rather slim, with a pale yellow to yellow-green to whitish cap and buffy-white to pinkish or lavender-gray warts”. Warts to me could be construed as “buffy-white”.

This shows how much I need to learn about photographing Fungi. The second and third photos are of the same specimen. Goes to show that 7pm isn’t a good time for pictures without accessory lighting. Unfortunately, with my teaching schedule (8 classes) evenings are about the only time to explore the woods any more. I’ll practice over Labor Day weekend with the aluminum foil.

I think that is a possibility…

Yes, Noah, I’d want to know the size and shape of the spores before anything else in dealing with a specimen like that depicted in this observation’s pics. However, my experience with long striations on the cap margin in the gemmatoid group in the eastern US would suggest species S1 and A. russuloides as strong additional possibilities (if, indeed, the latter two prove to be different taxa).

would this be something close to praecox?

I don’t think this can be citrina….

The cap margin in the first image is distinctly striate at full size. The bulb in the second picture (despite being out of focus) is not marginate. The volva on the cap and the edge of partial veil in the third picture is bright yellow. Hence, none of the pictures can be of A. citrina in any sense of the name of which I am aware. There do seem to be two different species in these pictures. The bright yellow volva in the bottom pick is not present in the top two pictures even though the bottom specimen seems to be the most mature of the three (and, hence, would be the most likely to have lost the yellow pigment by bleaching or rain or….). I suggest posting the third picture separately from the other two.

Looks kinda like species S1…


Can you get any pics of the base?
