I’d still love to see the description of this variety.

OK … When are, please write me exiccatum and private sectors. Now we’re doing molecular species. It is possible that we raise the variety to species rank independently.

I am almost home from my travels and I have numerous collections of this, so I will look at it once I set up the microscope. So far all I have seen for these are spore measurements. A photo of the spores is here on Dimitar’s site:

Dimitar notes somewhat smaller spores (6-8 × 12-14µ) than observation 32853 (7.2-8.0 × 14.4-16.5µ) and observation 33397 (7-8 × 14-16µ).

I can also send collections for you to analyze, but I need to find them, as I have been away from home for 4 months.

Microscopic data need to confirm 100% that is the sort. Macroscopically it appears, but always keep in mind that Psathyrella marcescibilis var. virginea is a European species, and usually in America you have always double species, but different. I’ve already mailed my work on this species, check the microscopy. I can not do anything else from here …. If you can send me some samples and I will analyze them. It could be the first appointment to America, if you want to do together and we published an article on a European areva. Write the private sector.

It was not my idea, but it seems to be the best match. See discussion on observation 48743. Antonio gets all of the credit for solving this mystery! :)

how did you make this ID Erin?

This is the undescribed species. Nice fruiting! You should dry an herbarium collection.
