but amanitas do grow from roots, just not usually from exposed ones!

last year I found the most curious fruit bodies on the exposed roots of a downed tanoak…they were round and areolate, almost puff-ball like in appearance. i took one home, and waited, and waited, and surprise! it hatched into a coccora.

Stange for an Amanita

I agree, the conjunction of white gills and striate margin screams Amanita.

I found this mushroom growing from a large above-ground root of a tree in a pine plantation. The mushroom was growing out of a crack in the wood. I have never seen a grisette or any other Amanita growing directly from wood.

This observation is not as complete as I would like. The remnants of a hurricane blew in as soon as I found the mushroom. It got dark very quickly, so I had difficulty getting a good shot. The pine trees were whipping around like tall grass in a windswept field, and branches were falling all around me. I only had time for the two snap shots here before I decided to run for cover.

Something to look for next year eh.

Fine hairs on the cap? Spore print it?

The margin does appear to be lined in your speciman, so I doubt Volvariella taylorii.I do doubt that you would confuse Amanita vaginata for a Volvariella though.

it’s exciting to think that this may be a volvariella…

but I have to say that I agree with Darv. Other than growth habit, it has the dry, grayish striated cap of a grisette, with a long cupule of a volva and the red-orange staining is common too…

altho unusual to see, these mushrooms do originate from the roots, and sometimes
those roots are pretty close to the surface.

I’ve never seen a wood-dwelling volvariella, but I would love to, too.

Looks like an Amanita with whitish gills. Only one Volvariella is known to grow from wood and it’s from hardwoods, not Pine.

Only know 2 species: V. volvaceae and V. bombycina. Need to look at it again with books in hand.
