Observation 302397: Amanita lavendula group

When: 2017-12-10

Collection location: Greenville, South Carolina, USA [Click for map]


No specimen available

Found in an old rotted log on 12/10. The log crumbled when I took the mushroom out. It looks like an Agaricus or possibly an Aminita but it doesn’t seem to match Simon & Schuster’s mushroom ID guide. Sporeprint white. Doesn’t seem to bruise, doesn’t have an unpleasant smell. Bulb on root. About 5.5-6" long.

Thank you everyone so much for helping me figure out the specimen. I very much appreciate Rod & everyone’s expertise and feedback, I’ll definitely check out those links and study up!

this looks so much like phalloides!

in that first shot.

it takes time to learn your amanitas, in all of their guises.

A. lavendula fooled me the first time I saw it in the field, too.
we only get phalloides here in the West.
This mushroom used to be called citrina and it sure was/is citrine.

Your reputation precedes you. I’m honored to be able to learn directly from a gentleman held in such high esteem as yourself. It’s not easy teaching yourself this subject matter and that’s one of the reasons I love MO. It’s such a nice thing to be able to be in the presence of such knowledgeable men and women. Thank you sincerely.

Amanitas have two forms of development.

In the primordium, a solid mass of tissue in which the mushroom takes form, the cap, gills, and stem may either develop relatively centrally or very much eccentrically. In the latter case what will be come the mushroom begins a slight bump on the top of the primoridium. For these amanitas, the development of the mushroom can progress to a state in which the mushroom at maturity has a bulb at the base of the stem. In other species, there is no bulb at the base of the stem because the mushroom starts growing more nearly centrally in the primordium and the lower part of the primordium becomes the bottom of a stem enclosed only by volva.

An example of the first form of development would be Amanita muscaria. An example of the second form of development would be Amanita jacksonii.

Very best,


About the base…

Well if it’s a bulb than its not amanita. But the essential Amanita cup can be tricky at times. Looks very much like an Amanita bisporagia…though I’m no expert.
