Proposed Names

-9% (3)
Used references: This mushroom was found on a foray that Italian mycologist, Silvano Pizzardo organized with Ennio Giusti and Albert Casiero. It matches the description and photos of Amanita boudieri Barla which is described on p.42 of his book, “Funghi del Bosco della Mesola” as similar to “Amanita baccata Fr., but is different in characteristics, among others for the elongated shape of the spores.” Silvano Pizzardo is “Coordinator pro tempore” of the Federation Veneti (Mycology) Groups.

but the actual Italian field biologist who handled this lepidella thought otherwise.
and he would’ve been the only one to look at the spores (it looks immature though, doesn’t it?).

I think that James was merely referencing the description of spores, not an actual slide of spores.

Amanita velosa is a western NA springtime amanita…that we now see in November.

that was my point.

w/out the hard data (ie a fruit body) back-up though…it’s conjecture.

Well,… somebody checked the spores…

Apparently, the baby had a chance to grow up a bit. Does it still exist somewhere? I see James came up with the name gracilior especially because of the time of year in which the collection was made. The big Neville and Poumarat book makes a great deal of the seasonality of the two species.

Very best,


are there staining differences, too?

the Italian amanita book that i have here also states that there are differences between the two in annulus position (medial vs apical) but that seems like a pretty variable trait.

but w/out a fruit body, this ID is just a rumor!

The two species can also be …

separated because one has clamps and the other lacks them.

Deprecation on MO is not the same as taxonomic or nomenclatural (a spelling error or an error in author citation can be deprecated and retained, for example).

You should be aware that the www.eticomm.net site is going to go away in favor of the new site.

On the new site, you can find gracilior at


The only reason the old site is being retained is that a few checklists and keys have not yet been moved. The old site is not being maintained and hasn’t been since the last week of September 2010.

All named lepidellas (of course, “so far as I know” is the caveat) are listed on this page:


If you’re interested in Amanita, it’s worth learning something about how this site is organized. All the old description in non-technical language have been moved to the new site, and many have been added. Now, we’re at nearly three-quarters of the species having substantial technical descriptions as well.


I dunno Jim…

I’d go with the local Italian expert and his name, first, especially with two lepidella species that are so darned similar in their macromorph.

If ya haven’t noticed, those set in stone times of fruiting are changing everywhere, both in Europe and North America.
