here in Olympia were extremely scant this summer down in South Puget sound also…
Found and posted a few in spring season but none of the summer to late summer flushes that we are used to ever appeared. So glad to see this observation and know that I can hopefully start seeing the beautiful red troops starting to pop up soon :)

Really great pics Tim!

I have seen very few Amanitas this year…

A scant few A. franchetii, a few A. constricta, a couple of A. muscaria var. flavivolvata, one A. muscaria var. muscaria was brought into the clinic, and a nice chunk of A. phalloides.

Not one. Single. Panther.

Beautiful photos Tim!!!

Our spots here in Olympia are just starting to show buttons but none at maturity yet…

Thanks Charles!

The Eurasian and North American red fly agarics

can be segregated by microscopic characters. Spore length, spore shape, and thickness of certain elements of the gill trama measured in a well rehydrated gill cross-section are three quantitative elements that are known to differ.

Macroscopically, you have to deal with a great deal of variation.

The subspecific epithet “flavivolvata” gives the impression that the North American taxon would have a yellowish volva and, perhaps, the Eurasian red fly agaric would not have a yellowish volva. However, this is false. The neotype of muscaria had a yellow volva. The type of flavivolvata had a yellow volva. In both cases the color of the volva (especially after exposure to UV light can be very, very white.

At the present time, we know the two taxa are segregatable by molecular means and segregatable by study of microscopic morphology the 2008 paper by Geml et al. Demonstrated the molecular component of this information. Although it will be treated in a future publication, the differences between subsp. muscaria and subsp. flavivolvata are to be found on the technical tabs of the two taxon pages on




Very best,


Many trees in Seattle

Many trees in Seattle are non-native, and Green Lake probably doesn’t have a single original (pre-1905) tree left in the park. Much of what is park today was under water prior to changing the outlet, dropping the water level, and filling parts of the lake. It would not surprise me if there are European mycorrhizal fungi there.

I am not sure….

But I imagine they could very easily be introduced trees.

Boy, this looks like the European version…

What trees were around?

This was observed during….

A walk for suicide prevention. Everyone was walking around the lake, and no one noticed these beauties. My fiance and I saw them from 50+ yards away.

It was great, as soon as I walked off the path into the grass to begin shooting them, suddenly everyone walking took interest. It is crazy you could walk by something like this without even seeing it!

Hey, I used to do the same….
