I believe this fits macro traits associated with “series Penetratrices”.

Thick/hard umbo on the disc, deeply rooting stipe, persistent membranous volva, relatively large fruit body.

Oak dominated woods, maybe 15-20 feet away from obs 281997, but this one looks a little different from 281997. Globose to subglobose spores are smaller than 281997, ~7-10 × 7-9.

Colors in photos are accurate.

Very exciting possibility. As you noted.

We are very glad to get this one, which happens to be the last one I processed in your last shipment.

Thanks very much for a good set of specimens.

Very best,
