Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
In case anyone is using an older book, this is the species that for a long time we called E. truncata, while the name "Exidia glandulosa" was wrongly applied to the fungus we now call Exidia plana.
The latter has a more convoluted, "brain-like" appearance.
