Brief Description:

The cap color is variable, but is typically olive-green with a metallic sheen. However, the cap color can be yellow green to yellow, grayish, brownish or even pure white. The cap often appears to have dark fibers, but these are due to narrow bands of pigment rather than actual fibers.

The cap is often palest at the margin (for example white or extremely pale yellow or extremely pale yellow green). The cap starts out egg shaped, exapands to rounded and eventually can become nearly flat. The cap is typically smooth and shiny when dry and can become a bit sticky when moist. At times the enclosing volva leaves a white patch on material on the cap.

The flesh is white and unchanging when cut or bruised. The gills are white to cream, crowed and free to narrowly adnate.

The stem is white to pale yellow below the ring, sometimes more strongly yellow near the stem base, sometimes with faint yellowish white areas above the ring. The ring is typically on the upper part of the stem and forms a membranous veil often with fine striations. The base of the stem usually forms a bulb which is wrapped in a sack-like volva.

The odor is sometimes absent in early development, becoming strong and unpleasant in age.

Looks like the consensus at this point is Amanita phalloides (Fr.) Link so I’m going with that and moving everything over to that.

Rod, I removed Vaill. because of comments you’ve made in the past regarding the naming of this species, you do not cite him on your personal website either.

I’m interested to know why your changing your mind about this now.
I was only following your recommendation when you said Vaill. was not valid.

Species Fungorum shows the current correct name as
Amanita phalloides (Vaill. ex Fr.) Link

Reapproving since this is not really deprecated. If the community decides to remove the sanctioning author, then I can do it on the back end so we don’t end up with mix of names.

I agree with Rod on keeping “Vaill.”

I thought the only point up for debate is the " : Fr." bit. I voted for dropping it for simplicity and consistency.

However, I don’t feel really strongly about dropping it since it conveys some valuable information. In particular, it tells me this is a really old name based primarily on macroscopic features that probably doesn’t have a useful original type collection.
