Observation 109184: Amanita amerirubescens group

When: 2012-09-07

Collection location: Hickory Run State Park, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

Some examples of A. flavorubens are easy to ID. Some look a lot like A. flavoconia, until the brown staining in the stipe base is seen. But the ones that look a lot like A. amerirubescens can be perplexing… Although I’m basing my “flavorubens” proposal on the yellow tones seen on the cap surface, in the patches, and on the stipe, I’m undecided about this one.

Perhaps if I had examined the stipe base for the granular yellow deposit?

Sometimes, the reddish-brown staining…

on either flavorubens or a Blusher may only be seen on the context inside the stipe base, especially on a young/undisturbed specimen. For this one, there’s blushing on the cap surface. I think this is one of the amerirubescens species, and except for the possibility of flavorubens, I see no other reasonable proposal. Found in an area of Hickory Run SP that gets inundated with flavorubens. So maybe this influenced my initially leaning toward this species proposal.

to be some red staining on the stipe, but hard to tell.
