Weather effects on color of mushrooms.

Dry, wet or cold weather can effect the color of mushrooms.

The color can be leached out of the cap of a Fairy Ring Mushroom by heavy and prolonged rain.

Cold weather effect on color of cap.

A Birch Bolete will turn brown instead of orange red. Will hardly stain when cut.

Weather can have a profound effect upon the appearance of a mushroom. The pure white bolete seen here is probably Xanthoconium seperans, which is usually pinkish, tan, or brown.

That first Amanita looks from the top to be something related to a Panther type. But the large elongated rooting stipe-base looks like a Lepidella. The brown stains on the lower stipe of the Yellow Blusher are a good characteristic for A. flavorubens. Do you know the tall grayish Amanita with the small rounded bulb? My first guess would be "Amanita solaniolens."

There are lots of Leccinum species... some are red, some orange, some gray, some brown, some white. Many types grow with birch.

Dave,

I got interested in Amanita only this past year, mainly because the mushrooms were relatively scares. Up to this year I had the mentality of the beginner which is if it is an Amanita it is not worth a second look. The Fly Agaric is the one that is most common over here and the only one I can ID with any certainty. Thanks for the two names, I will add the possible ID to the page. Like I said, I like to have scientific names attached to the pictures but I am not obsessive about it.

I am not sure which Amanita you are talking about when you say “tall grayish Amanita” but will assume you mean the one on the same page as the Yellow Blusher and tagged as Amanita #3, here

It was pure white in color except for the cap.

You have no Idea what Amanita #4 is? That one was a surprise. It looked like a prune. I was surprised how dried out the cap was on top but yet the gills still looked fresh.

Here is what happens when it's been super dry and then you get a downpour of rain! The entire first bolete crop was distorted like this.

Then this is what happens when they are super dry: they crack up
