Pakim pond ensis. Actually, it flows nicely off the tongue.

I think we should say “a potential holotpe” instead of “the holotype.”

originates from a location in Brendan T. Byrne S.F., Pakim Pond, where a potential holotype of this amanita species was found. It’s about 2 miles to the east of the park office as the crow flies. The pond area is also known for a rare and unusual bolete, B. purpureorubellus.
My preference for the accents falls on the first and fourth syllables, but I could be wrong about the actual pronunciation of Pakim.

I think I may need…

a pronunciation key for this one :-) I’m guessing accents on the second and fourth syllables. How does the name translate to English?

The more I learn, the more I realize I don’t know or the more I realize that what I am searching for is not available.

Very best,


Thank you, Rod

Well, if it weren’t for your tremendous Amanitaceae research and your awesome website, I would have never been able to propose this ID, which is true for most amanitas for that matter. :-)
I think “sp-56” happens to be the only Sororcula-type grisette known from the NJ Pine Barrens so far, so it became an obvious choice and a reasonable guess. It’s surely nice to get the ultimate confirmation from the molecules. It doesn’t get any better than that!

The voucher for this observation yielded very good quality nrITS and nrLSU sequences.

The match to Amanitasp-56” is 100%. Good going, Igor! That was a great suggestion for an ID—-“right on the money.”

Very best,
