Thank you again for your recent shipment. We hope to get this material sampled for the winters sequencing project.

I would suggest separating the two specimens into separate collections when they are separated by some distance in nature.

Just an extra caution.

Very best,

then the second and third photos would belong to maryaliceae and the first and last would belong to a var. alba.

The partial veil

seems concolorous with the stipe, and as far as I can tell there is no difference in color between the top and bottom of the PV.

I wonder if I don’t have a mixed collection. In addition to the apparent staining, the bulbs seem different. Additionally, while the two fruiting bodies I held onto were near each other, they weren’t under the same tree.

The bottom of the p.v seems gray. Is that just shadowing or is it a real thing?

Very best,


No, it is an unstaining species.

Is their yellow on the underide of the partial veil?

If not, it might be rubescens var. alba. The spores can be a bit helpful on that entity…unlike other rubescent taxa.

Very best,

I’ll send it your way.

A quick question. One of the fruiting bodies has some reddish staining on the bulb. Is that common for this species?

Could you include this in your next shipment? I’d like to see if I can resolve the DNA situation with maryaliceae.

Thanks very much.
