Observation 49839: Amanita Pers.
When: 2010-08-07
Who: smilacina
No herbarium specimen

Notes: found growing near slash pine and saw palmetto, on the edge of dune grass habitat. i accidently broke the bottom off when i was digging it out. i thought it might be an Amanita, so i checked for a volva, but it was so squished and sandy i couldnt tell. Definitely didn’t have an Obvious volva.

unfortunately i wasn’t able to go back to that location, and i never found another one on the islands. I appreciate all of your information, nonetheless, and if i ever get back there, i will collect what i see!

Absolutely worth getting another one and drying it for examination…

My guess is that, if this is an Amanita (and I agree that it looks like one), it may be one of the very narrow-spored species of section Lepidella. If you find one to collect, check to see if there is a well-defined pileipellis between the volval material and the flesh of the pileus. The pileipellis (if there is one) is going to be composed entirely or nearly entirely of hyphae that are vertically compact and run along the general curve of the cap surface. The volva and the cap flesh will both contain inflated cells. Sometimes the tissue in the volva can be organized with a lot of elements roughly vertical. This is never true of the cap flesh, which usually is an open matrix of hyphae with inflated cells having their longer axes roughly aligned radially in the cap.

I once found a specimen of A. rhoadsii that looked a little like the last picture in your observation. That doesn’t mean that that’s what you have. There are one heck of a lot of lepidellas in the Coastal Plain of the Gulf.

If you find this again, cut it vertically so that we can get a feeling for the color of the gills. Some of the species I’m thinking of as possible IDs have a distinctly non-white gills. Like the cream-yellow gills of A. subsolitaria, which is apparently related to A. rhoadsii according to Bas’ 1969 monograph of the section.

I hope you’re able to get some clean-up work done. My best wishes are with you.

Very best,

Rod

Christian. any hope of further id? is it worth going back to the island to collect so i can look at the spores and stuff when i get home? i’m down in the gulf islands working on the Oil Spill at the moment. no one has ever done a fungal survey of these islands…………….
