Identifizierung

Deutsch: Der stiel von diesem Pilz ist gelb und meiner Meinung nach muss er einer Kaiserling (Amanita caesarea) und keiner Fliegenpilz sein.

English: With its yellow stipe, in my opinion this must be an Amanita caesarea and not Amanita muscaria.

With no doubt this is Amanita muscaria.

Please, correct the name, as can lead to confusion (intoxication). 188.171.200.212 22:49, 14 November 2022 (UTC)

Hello,

A more or less yellow stipe is not distinctive between Amanita muscaria and Amanita caesarea.

Many forms of Amanita muscaria have yellow stipe, and some even have a yellowish cap. As example, you can search photos of Amanita muscaria var. formosa.

You'll never see a Amanita caesarea with small rests of universal veil forming dots over the cap, as can be seen in the Amanita muscaria of your photo.

The reason is that the universal veil of Amanita muscaria is formed by a good percentage of more or less globose cells. When the mushroom grows this veil breaks in a lot of small dots, that remain in the cap and base of stipe. Due to this Amanita muscaria lacks a well developed volva at the base, and has a lot of small rests of veil as small concentrical scales on the cap, and also on the base of stem.

In Amanita caesarea the universal veil is mainly formed by long cylindrical cells, with only a small percentage of globose cells. Due to this the universal veil of Amanita caesarea is much stronger, and remains intact for a longer time. After breaking remains as a well developed volva in the base of stem, and sometimes one patch on the cap (exceptionally two or a few patches on cap... but NEVER forming scales).

Finally... your photo was taken in a ¿Picea or Abies forest?, in Bamberg.

I live in Spain, where Amanita caesarea is quite common, mainly under Quercus, Castanea... mainly in Mediterranean climate areas. Is a fungi that I've collected many times (not as much as Amanita muscaria), and I've a good first hand experience. But as this experience can't be proven in an internet message, I'll refer to other sources.

Amanita caesarea is a very rare fungus in Germany, as is stated in the red list. Finding it could be really uncommon.

In the series Die Grosspilze Baden_württembergs (Volume 4, pages 10-11), they say occurs under Castanea, Fagus, Pinus and Quercus (no reference to Picea, Abies... as wet coniferous forests aren't a good place to find this fungi).

They have only 13 references of Amanita caesarea findings. But they compile information of more than one hundred years... On average was found one time each 10 years!

- Two times in 1878

- 1932-1934

- 1948-1951

- 1977-1982

- 1989

In the work "Verbreitungsatlas der Grosspilze Deutschlands (West)" (Band 1B, page 487, plate 87) can be seen more findings of Amanita caesarea, as cover all West Germany (book was published in 1991), but still remains as a rare fungi.

For sure, if you have the luck in future of finding Amanita caesarea, mycologist of your country could be more than happy if you advise them of the finding.

In this case you could contact the DGfM:

Feel free also to contact them, and ask them to confirm if what I'm telling you in this message is true, and if they consider that your photo depicts Amanita caesarea or as I've stated depicts Amanita muscaria.

Note: Who knows if in the future, due to global warming, Amanita caesarea can become a more frequent fungi in Germany. But to date, in your country, findings of Amanita caesarea are very uncommon.

Friendly regards,
