Notes: This mushroom was growing by itself on a dry flat upland area under mixed hardwoods. The bottom piece of the bulb broke off while I was digging it up, but I reattached it with a toothpick. This mushroom is about six inches tall.

A checklist shows that someone endorses a name, but it doesn’t tell why. I’d really like to know why the name is preferred. If there is no argument, the last expert to give a considered opinion is still Dr. Bas.

Amanita echinocephala

You can find the the data at the URL in my original comment, its source being none-the-less than the British Mycological Society on their Species Checklist database. It is one of these species where different authors do not appear to be singing from the same hymn-sheet, but they usually follow the BMS lead in due course, even if under protest. Of course I am assuming the database is not out-of-date.

The only one I have found to-date was earlier this year at Eastbourne, East Sussex, England

Amanita echinocephala is not the proper name for the European mushroom….

that is called “A. subsolitaria.”

In 1969, in his thesis which is still the world’s most important work on Amanita sect. Lepidella, Dr. Bas selected A. subsolitaria as the proper name for the European species in question. He provided both his argument and his doubts about selecting the name. The mere fact that he considered several alternatives is not a reason for rejecting the name. He considered them and made a choice.

I am quite serious in saying that if there is a sound argument for the use of the name “echinocephala,” I would very much like to know where it can be found. I will read it with interest and attention.

Very best,

Glitch in the naming matrix?

I also tried to create the name Amanita echinocephala. I do not think it is a match necessarily, but I like to see the many possible names listed because it generates discussion.

The error message said “The name ‘amanita echinocephala’ was not recognized.
Click ‘Create’ to create this name or edit the name below to correct any typo.”

Clicking create again gets this error message: "Unable to create the name ‘amanita echinocephala’. "

I’ve seen the same problem with other names, but I do not know what is causing it. Amanita echinocephala is a real mushroom with it’s own nice wikipedia article.
http://en.wikipedia.org/wiki/Amanita_echinocephala

There should be a home for this name at MO imo.

What’s going on here, a technical glitch or some dark conspiracy ?

The mushrooms you’ve proposed are European taxa and are not found in the U.S.A

Amanita solitaria

FYI Amanita solitaria is an excluded name in the British and Irish basiomycota checklist run by the British Mycological Society , see
http://www.basidiochecklist.info/Names.asp
But as Mushroom Observer would not allow the entry of A. echinocephala chose the historic option; even though it may be technically incorrect

Due to the pointed stipe base I would go for Amanita echinocephala, assuming it is found in the States. In the past A. strobiliformis has ofted been confused with A. echinocephala, both species have often been determined as A. solitaria (a nomen confusum) thus the true distribution and frequency are uncertain.

The one I dug up earlier this year also snapped the stipe (due to it being entrenched much deeper that I expected) whilst trying to prise it out with my mushroom knife.
