This is the closest tree, I’ve not been able to identify this tree by bark, I will attempt to ID it when it leafs out.

Yes, DNA should settle the argument

Molecules never lie, but our current understanding and interpretation of molecular data may not always be accurate in these early days of DNA-driven phylogeny – there is always a bigger, unseen picture.
Based on what is currently known about the distribution range of prava, and the fact that this collection was made in TN, americana is a more reasonable proposal.
I see this collection has been preserved, so it could in theory be sequenced to seek an unequivocal ID and to probe the potential southern range of prava.

tough call.

how deformed is deformed enough for prava? we are asking this same question here in the west.

both hardwoods and conifers are present here, so no help there!

M. californica is a synonym of the preferred M. americana (Kuo’s esculentoides).

I’d say it was a toss-up between prava and americana. Only the DNA will tell you for sure, in this case.

Good point Christine.

I’m still getting use to the ideas… calling the eastern NA big esculenta look-alikes esculentoides, except for this oddball species prava; and awaiting more info regarding the distribution of M. cryptica.

My own take is this… except for ones that appear to qualify as prava, I’ll call my local types esculentiodes until if/when cryptica is shown to occur in my region.

M. prava

Maybe M. prava would be a better name here? These look a little darker and the pits a little more convoluted than would fit for M. esculentoides?
