I had no idea there were no true A. citrinas (or A. bulbosa var. citrinas) in the US. Very good to know.

I think I know what you mean by the plaque-like volva vs. the small warts now. I’ll see if I can’t find any more of these mushrooms in the future, and I’ll be careful to get the bulb out.

Thanks again for all of your help!

Amanita bulbosa var. citrina is

the same taxon that was called citrina (and still is by lots of people). It is found only in Eurasia and not in the U.S. However many citrina-like taxa we have in eastern North America (one or more), none of them is the same as the European taxon so far as I know.

This mushroom really can’t be any of them because they all have a thin, flat, plaque like volva on the cap. Without the bulb and with the cap edge still turned under (making it unknowable whether the margin would be striate at maturity), it’s hard to say what section this might actually fall into…although a whitish cap with small pale warts in the state of Florida does have odds favoring sections Validae or Lepidella.

Very best,

Very interesting. Thank you for the help on this one :)

The volva on the pileus of species similar to A. bulbosa

is more plaque like and tends to become brownish or brick-colored on exposure; the volva on the cap in these photos takes the form of small, isolated warts.

Too bad about the bulb getting left behind. A trowel, an aluminum tent peg, a bowie knife, etc. is a good thing to have with you for excavation of bulbs. Not to mention a shovel crew when it comes to deeply rooting lepidellas.
