the Bessette, Roody, Bessette, Dunaway Southeastern US book.

There’s a pretty nice picture of one they are labeling A. ravenelii

BRBD? Bill Roody’s book?

Another feature to consider! The image of A. ravenelii in B-R-B-D certainly has a similar bulb.
My specimen is a little old and abused here, but easily one of the biggest I’ve seen.

Of course, I have definitely found a lot of A. rhopalopus in my woods as well.

This has been tremendous learning experience, I’m hoping – now that our rain has finally stopped- that our October is going to produce some good fun!

I’ll have a good box of specimens for you in the mail shortly.

You may have heard that we had two BIG lepidellas at the NAMA 2015 foray.

The two species involved were A. rhopalopus and A. ravenelii.

These can be separated by a 10x hand lens because the latter is distinguished by an entirely hyphal base layer of the volva on the cap. With the help of the hand lens, you can see the layer of white fibers interconnecting the warts on the cap of ravenelii.

I couldn’t get a high enough magnification on your images to see if they could be ravenelii.

Very best,

Rod

OH no, sorry, sir.

I went no further digging this one up in the rain. I mainly shot it for the big pyramidal warts, and huge size of the specimen. The bulb looks split horizontally and vertically, and I was surprised by the dark staining of the stem.

Can you tell us anything about the shape and size of the bulb at the stem base?

The form and size of the bulb is very useful in sect. Lepidella sensu Bas.

Very best,

Rod

ah yes

the partial veil as you can clearly see is nothing but bits on the ground.
This was one huge mushroom!

The partial veil has fallen to the ground. >>EDITed

The partial veils of cokeri and subcokeri are membranous and persistent. This is probably a different species.
