split bulb on…

Ryane,

I noticed that the underside of the annulus is gray in the first photo and there appear to be gray remains of the universal veil on the stem. I think that you might consider Amanita porphyria as a possibility.

In the east, we often see specimens of the “citrina-group” with vertical splitting on the bulbs especially when the bulbs are firmed up very tight in a moist environment.

The abruptness of the bulb in _brunnescens is more pronounced than in this specimen (the edge of bulb’s top is near or at the broadest point of the bulb in brunnescens); and brunnescens would develop distinct staining around all the insect damage.

So far as I know at the moment, _brunnescens only occurs in eastern North America.

So I am inclined to vote for porphyria.

Very best,

Rod
