Observation 266996: Amanita magniverrucata Thiers & Ammirati

When: 2017-01-10

Collection location: Cambria Pines Rd., Cambria, California, USA [Click for map]

Who: Aaron Jackson (aaronjackson)

No specimen available

I found two examples of this species today, one small (~3" cap diameter), and another much larger (~5" cap diameter and quite heavy!). Both were growing independently, but about 200 yards away from one another. Neither veil had released from the cap yet, so gills were not visible yet. Looking under the cap, young gills are large and white. Stalks are very thick and dense, with multiple rings running around the circumference. As seen in photos, scales are rather pronounced. No yellowing upon cutting or bruising.

They were located about 1/2 mile from the ocean in a dense Cambria/Monterey Pine understory, not in a grassland area as they said to normally be found. Other mixed conifers and shrubs were also present.

Smell is pleasant, quite almondy, and the flesh is thick and firm. The cooked flavor of the mushroom is mild and sweet, and quite fragrantly almond-like, with a chewy, snappy texture. The fragrance/flavor of the mushroom persists for some time. There was a very faint bitterness, but not at all unpleasant.

Hello Fellow Observers,

Thank you so much for the proper id! As it was a mushroom I was unfamiliar with, I only samples a tiny part from the stem. 18 hours later, I do not have any symptoms but following your identification, I called a mycologist at UC Berkeley as well as toxicity expert Dr. Todd Mitchell in Santa Cruz, CA for assurance. Both told me that the quantity tasted and the lack of symptoms does not worry them much at all, but of course to monitor myself over the next 24-36 hours. Thank you again so much for the proper ID, and potentially saving me from a more dangerous situation!

I’ll stick to what I know from now on.

if you ate this in any quantity other than a taste and spit

best get yourself to hospital now. Its toxicity is unknown, but relatives in amanita section Lepidella have very serious toxins which can cause kidney failure.

Crocodilinus is a squat species of Agaricus with a short stipe and dark gills. They grow in open grasslands, not with conifers.

What you show is an Amanita section Lepidella, with only part of that very long rooting stipe collected.

AS to the odors you perceived … I imagine that’s just wishful thinking on your part.

These are NOT Agaricus!!!

This is a potentially toxic Amanita species.
