For true color, a gray background (“neutral gray” or “photo gray”) works best.

The grayish yellow range would apply to some species such as Amanita sinicoflava; however, I am not convinced that the upper part of the volval sack in your pix is turning gray, which would be the case in sinicoflava.


So I don’t have a really probable guess for a name.

Very best,


Phil, I think the camera is probably okay.

Getting acurate color is more a question of lighting and background. This is why I carry around a white translucent umbrella and a foil reflector when I go foraying.

As close as I and my wife can ascertain by holding “Methuen” to my computer, the color of both sections seems to be Greyish-yellow. "Methuen pages (2-3)B(3-7). A difficulty in stating the precise color is that my Sony 7.2 mega pixel camera takes photos that are much lighter than the actual specimens. Thanks for your assisstance.

Phil, thanks for calling my attention to these photos. FIXED TYPO

I’m having trouble telling the cap color against the bright green background. How would you described the cap color in the center? And about half way to the cap margin?

You’ve got the section nailed down.

This group is really hard in North America as a whole. So many species and so few names. We’re hoping that by May we may be getting some more information from [CORRECTION—>] genetic studies that will help us separate the taxa that we haven’t been able to separate so far. There’s a long way to go…that’s for sure. Dried material is always welcome (after the IRS deadline).

Very best,
