Thank you for this specimen, Eric.

We sampled it for sequencing and got a partial sequence for the “fungal barcode” gene. We failed to obtain a sequence for nrLSU (aka 28S) a second gene that is valuable in molecular studies of many organisms.

We have not yet identified rubescens var. alba with a single genetically defined group. There is much more to do. I very much appreciate your willingness to share your collections with me…and now with other colleagues as well.

Very best,

Rod

With the partial veil still in place, spores are probably absent. So this entity remains, for the moment, an open issue in terms of identity.

Well, then, you’ve probably got it.

The center of the cap isn’t darker than the rest. These mushrooms start out white/pale and then stain readily on the cap as they age.

I’m gonna vote “promising”

It’s just that I can’t be sure of the color of the very center of the cap. And spore measurements really can help separate Coker’s _rubescens var. alba from the pale tan of amerirubescens.

Very best,

Rod
