William was the original observer, but I only just now pulled this from the garbage pile of Fungi observations

Thanks for calling our attention to this observation, William.

The contorted form and scattered areas becoming blue is typical of the speciemens that have been discussed and pictured on the Amanita of North America fb group page.

Initial work at Duke Univ. indicated that a Hypomyces is involved. My own microscopy on some of the same specimens shows that there is no trace of Amanita tissue left in the distorted amanitoid-basidiome-like specimens. At least one bacterium is also present in deformed and undeformed specimens from one site.

I think the bluing amanita phenomenon is (in the cases examined) a real thing.

I also think that this specimen represents that thing.

If you should find it again, it would be of great interest to me or to Duke. The Duke contact is mentioned in material on the aforementioned face book page.

Very best,

Rod Tulloss

Need more photos, William.

Can you return? If so, can you take more photos? May need to dig the fungus, if it has a volva in the ground.

True.

I am not convinced the turquoise is natural.

I have used blue vitrol in the past for sheep dip after trimming hoofs for foot-rot. Nasty stuff.

Copper sulfate, which is a bright turquoise color, used in parks nearby to kill shrubs that were recently cut down. I don’t believe this is considered environmentally responsible, but I know in the last generation or two, CuSO4 was used widely, to control algae growth in ponds and fungal growth on crops. This looks a little like that to me.

both do not tend to be turquoise however

Not much to go on, William.

Need to know if there was a stipe (stem), and would have liked to see a cross-section of the fungus, too. My initial reaction is Amanita, my second reaction Calvatia. Seeing a cross-section would remove one of those reactions.
