My impression, as well.

The thickened/darkened umbo also points toward the penetratrix name/grouping.

This specimen really looks like A. penetratrix.

So much of the stipe seems to have been in the substrate….

Very best,

So much can go wrong. We could have mislabeled the sample on our end.

We’re darn lucky that things go right as frequently as they do.

Very best,

There’s always a possibility…

for mistakes to happen… digits permuted, wrong label placed into a bag, whatever. Assuming there was an error related to this observation, it may have originated on my end, really no way to tell. But the mushrooms seen here do not look like 208373. And the mushroom seen at 208373 looks a lot like the specimen representing sp-GSM05 on the AS website. So, it looks like there’s an error related to my observation (104501).

Maybe I can find this again. It’s an area I visit several times every summer.

Sorry about the lack of any useful result here.

Genes from this material (supposedly) have been obtained.

However, both nrITS and nrLSU are identical to those from a different looking species (MO 208373). I think there must be an error in the processing chain somewhere. We will try again after further investigation.

I’m Sorry about this, David. I’m disappointed, too.

Very best,

Rod
