Observation 9729: Amanita olivaceogrisea Kalaméés

When: 2000-08-10

Collection location: Garpenberg, Sweden [Click for map]

Who: Irene Andersson (irenea)

No specimen available

I would appreciate comments on this species/variety in the Vaginatae section. I haven’t found it myself, the picture is borrowed from a friend of mine. It’s not a big mushroom, the largest cap may be 60-70 mm broad.

Here is a link to pictures that popped up in a swedish forum, and I suspect that they could be the same (in a moist habitat with birch and alder):
Amanita fulva was suggested, also submembranacea, but I doubt both of them.

This is one way MushObs really is serving education, biodiversity knowledge, fungal mapping programs, etc. Irene borrows a photo and posts it after some on-line research. She gets confirmation of the ID. She goes back to the photographer with the information hoping to provoke a collection that will solidify the occurrence of the species in Sweden. This impacts mapping programs in Sandinavia, the Swedish checklist, possibly this also impacts the European fungal red list, etc., etc., and so forth (as the King of Siam says in “The King and I”). Look what you did, Nathan! MushObs is the new bugguide.com!


Wow! A new color for a grisette! Now to find that green coccora…;)

I will notify the people who have found this species, to save collections in the future. I realize that it’s the only way to put it on the swedish map..

I agree with the determination

Here is the brief description of the species on the Amanita Studies site.

In damp soil with Hazel is a typical habitat for this species. The author’s name is “Kalaméés”. It was originally described from Estonia and Latvia. If this observation was made in Sweden, that is a new country for the range of A. olivaceogrisea. Since I have seen hazel/alder bogs in Norway, I suspect that it occurs there also.
