we are all on a mushroom learning curve…

and I for one am loathe to give up some of these simple and common amanita names, like pantherina (sigh). I do understand the reasons, but I don’t have to like it! ;)

Don’t feel bad about mistaking this for a velosa, Weiliiii, we had three other folks this season do the same! Fortunately, they didn’t also eat their mistakes…

Cap color in both pantherina and velosa are variable, with velosa sometimes shading into brown (hen’s egg brown, just ask Arora!) or tan, and pantherina usually in shades of pale tan to dark brown, but never taking on the more typical orange or salmon tones found in velosa. both show white forms, but they are far more common in velosa. Pantherina tends to have warts or warts and patches, velosas usually have a single UV patch, but not always; sometimes they have warts, too. The volva on the stipe base is the big difference…pantherina has a close cup, often with a rolled edge, that fits around the rounded base of the stem; velosa has a loose sac that covers a totally elongating stem (ie, it has no bulb). velosa has no annulus and pantherina does (but this feature can be lost). oh yes, and one is a highly toxic mushroom and the other a choice edible. But you must take ALL of the mushroom features to make a good ID, and that takes time and experience.

I’m not so great at those wonderful east coast amanitas, myself, but I’m learning, too!

Aside from the base, the cap color is too yellow-brown (in A. velosa should be more coral to tan). In A. velosa the universal veil on the cap is usually in one or only a few pieces, and is much thicker – some parts of the UV on this mushroom look “frosty”, which is fairly uncommon (rare?) in A. velosa.

Sorting out

I’m still sorting this out, in the old days it would be called a A. pantherina. Now it is A. pantherina group because it is not the european species. What would determine it to be A. ameripanthera?

reminds me of…

This reminds me of Amanita velosa, I have not seen this species in person before and am not that familiar with west coast Amanita species, but that is what it resembles to me.

I guess the base would be wrong for A. velosa though.

Beautiful pictures though, sorry I cannot help.
