Recognized by sight: this is our unnamed gemmatoid amanita, depicted by myself and others as breckonii on MO. lack of marginal striations in mature form eliminates breckonii. from Rod’s website: breckonii with “strongly tuberculate-striate margin at maturity”.

is this colloquial naming a MO convention only or a forerunner to a publication in progress?

but that cap color is wrong for breckonii, isn’t it?

This looks to be the mushroom that we have been calling gemmmata var. exannulata, with its yellow cap and oddly pinched and flaring volva. But I will let Rod chime in here if he’s around. These two mushrooms (breckonii and gemmata exannulata) have been a source of contention and confusion for a while now; probably the only way to resolve it is thru good collections and further lab-time study.

OK Ryane, it’s up to you, now! Dry those puppies…and get them to Rod; or save them and get them to me this Fall; I should be heading your way at some point this month.
