This material has been received and accessioned into Rod’s herbarium.

At first I had thought…

these were older versions (faded color, eroded basal bulbs) of the yellow ones seen here…

But the spores are quite different for the two collections.

Earlier this summer I made collections of similar mushrooms at another location.
In this spot (Hickory Run) the yellow ones were accomanied by amanitas that were more of a tan color. Eventually, the area was inundated with a large fruting of A. crenulata. As the crenulata frutings increased, the yellow ones slacked off. So I’m wondering if there may be some relationship between the yellow type (possibly spS01) and A. crenulata. Some versions of crenulata seem to have relatively large patches on the cap that are readily washed off by rainfall… or at least I think they’re A. crenulata.

In the Sweet Valley location where I made this more recent obs (114779) there were some A. crenulata fruiting not far from where I made this collection.

Spores for 114779 are not amyloid.
