Yellow-orange staining is not a common thing in sect. AmanitaEDIT

to my knowlege. I can’t think of a single case. It could be the yellowing syndrome (which is most common on lepidellas).

Ignoring the apparent staining reaction, then I would say that A. velatipes is quite similar to the mushroom in the photos. The marginal striations are rather long for most of the velatipes I’ve seen, but my notes indicate that I’ve seen at least one specimen that I thought was velatipes that had marginal striations as long as half of the radius of the cap. I’ve mentioned before that for some reason I have rarely collected velatipes. This is not the case with many other folks I know…including Walt Sturgeon. So I would give some added weight to Walt’s suggestion of velatipes.

On the page

http://www.amanitaceae.org?Amanita+velatipes

on the techtab (near the bottom), we mention finding that there seemed to be two distinct sets of spore widths in collections we have attributed to velatipes.

It would be interesting to see what we could learn from Justin’s collection.

IDing the image is one project, and IDing the cause of the yellow-orange staining is another. We’ve never really gotten a handle on the causative agent(s) of the yellowing syndrome….

The yellowing syndrome is discussed on WAO on the A. subsolitaria page:

Very best,

Its highly unlikely to be an anomaly or genetic mutation, I found multiple specimens if these. I can add pics after work today. 6-7pm EST

Except for the brown staining…

this looks like velatipes to me. Is there a brown-stainer amongst the Pantherinae? Not that I know about. Could the staining just be an anomaly?

with reddish staining reactions from Florida? Not so sure.
