Amanita spissa var. alba

Common Name: No Common Name

Synonyms:

Substrate: Ground

Location: Hardwood Forests

Spore Color: White

Gill Color: Whiteish

Comments: 

Said to be a very uncommon species in the US, although we found it in several different locations in Indiana in 2012. It does not really have any information available online; there is not even a page for it yet at amanitaceae.org. One of the key features to look for are yellow-green tones around the outer edge of the cap and the unique remanats of the universal veil that are left on the cap. Some specimens may also present a bit of red staining, although I am not sure how common that is. 

Some comments from Rod Tulloss from amanitaceae.org follow::

"This is clear not the same taxon as those proposed by European or South American authors under the same name. Coker’s combination is not valid, but it is the only available name for the white species he described. The species is poorly known because there is no extent dried specimen of the type collection.

I believe that I have found this species (many years ago) in New Jersey. At the time I’m sure I confused it with Amanita canescens, which was not yet named."

Lookalikes:  

Amanita cokeri and A. subcokeri are similar, but they lack the yellow-green tones to the cap. They also will usually have a more elaborate structure to the partial veil.
