Observation 174888: Amanita polypyramis (Berk. & M.A. Curtis) Sacc.

When: 2014-08-22

Collection location: Groton, Massachusetts, USA [Click for map]

Who: Jim B (yakhunter)

No specimen available

Hi everyone. I found this mushroom on a hike and took some pics in the field. I went back a day later and collected it. It was in an area of mixed hardwood and softwood, mostly red oak and white pine. It was under pines in sandy soils on a banking for a woods road adjacent to a field. Groton, MA which is in Northeastern MA near the NH border.

When I went back to collect it, the cap was more open as you can see, The big one in my kitchen is the one that I took pictures of in the field. The little one in my kitchen was growing adjacent to the big one. It opened after I got it home.

Spore print was white to cream. Smells sort of spicy but not as strong as Matsutake are supposed to smell from what I understand. I think it smells like a deer or a boar, but that is just me. Spicy/earthy/musty I guess is a decent description.

I was hoping it was a matsutake, but some online have suggested it may be an amanita and potentially dangerous.

Thanks in advance for your help.

HI Rod, et al.

SOunds like an amanita so I am not going to eat it. It is yours if you want it. It has been in a paper bag in my fridge since I found it. What do I need to do to dry it and get it to you.

Thanks, Noah.

If Jim, or anyone else sees what appears to be polypyramis with a partial veil that appears to be strong enough to pull up fibrils from the stem surface, I would very much like to receive a dried sample of such a mushroom for examination and study.

Very best,

I haven’t seen a young veil like this before, but I haven’t seen many young specimens before. My name proposal was based on the older specimens.

It was the Amanita on Cape Cod.

I admit that if there were something matsutake-like at that foray, it would have gone right by me. :)

I also was referring to the Amanita in the discussion of range.

We find the matsutake-like entity in October in the New Jersey pine barrens. Noah is more likely to have relevant information for Massachusetts.

I’m really focused on Amanita and Limacella.

Very best,

Hi Rod,

Thanks for your input. Just for clarification, are you suggesting that Groton MA is pretty far north for the Trcholoma I was hoping for or the Amanita that has been suggested? ALso, which of these did you see lots of on Cape Cod. I grew up there and still have family in Barnstable.


Groton is pretty far north for this mushroom…so far as I know.

Has anyone seen it farther north? It’s not reported for Canada that I know of. I’ve never heard of it from boreal forest in Maine. I don’t think it has ever come in on a NEMF foray in Maine. I remember there being piles and piles of it at that foray on Cape Cod in freezing rain and sleet…about 1 degree above freezing for the whole foray.

Very best,


People along the Massachusetts coast seem to see polypyramis a lot more than we do in NJ.

Noah, have you seen the fibers connecting the partial veil to the stem perviously? commonly?

Very best,


I have one concern…the partial veil usually is very weak and falls off the stem.

It looks like that happened in the kitchen photos; however,the veil having enough strength to pull fibers off the stipe is something I haven’t seen. Interesting.


Very best,
