Observation 91552: Amanita sect. Amanita
When: 2012-04-01
28.246139° -82.113025°
Herbarium specimen reported
0 Sequences

Mushrooms were only about 2 inches tall with caps about that same size in diameter. The size and yellow caps make me think A. citrina, but these had no annuli and were just so darn tiny.

They had to have a volva. They probably escaped from the volva with “aid” of a gelatinizing cap skin. The volva breaks up as the cap expands and the upper layer of the cap’s skin probably has cell walls breaking down so that it becomes a slippery layer. Although there are amanitas that don’t have this particular property of the cap’s skin, the majority do. Friction between the sandy soil and the volva helps pull the volva from the slippery cap. I’d guess that that is what happened in this case. A little rain helps too…it keeps the slippery cap slippery and can wash off volval fragments.

In Florida you may find several amanitas that don’t even have a real skin on the cap or have a cap skin that doesn’t gelatinize at all or waits quite a long time before gelatinizing. Amanita nauseosa and A. rhoadsii are in the first group; and A. farinosa is in the second group.

Very best,


Thanks Rod

Do you think the caps probably had volval remnants that got washed/rubbed off?

With the marginal striations and exannulate stipe,…

I think that it’s more likely to be something in section Amanita, maybe in the gemmatoid group.

Cute little critter.
