Regarding the ITS. Glad you were able to at least obtain a usable LSU and narrowed it down to A. rooseveltensis which would be my first confirmed find of this species! Thanks! Out of curiosity is rooseveltensis still being treated as a possible species complex?

We have very typical Amanita rooseveltensis from the voucher material…

Thank you, again, for sending us the interesting material from Maryland.

reminds me of a tiny caesar like A. virginiana. And, except for the lack of an annulus, this petite mushroom resembles some of the virginiana pictured on the Amanita website. But, the finely textured stipe surface shows no sign of disturbance from a fleeting partial veil.

The voucher material for this observation has been accessioned in our herbarium.

The delicate specimen arrived in good order.

Thank you for sending it. It will be sampled for sequencing.

Very best,

Rod
