Collection location: SE 76th and Division, Portland, Multnomah Co., Oregon, USA [Click for map]
Same clump as obs. 117810 taken 11/24. This collection is starting to show some orange-brown as well as brown. It is also showing more predation, possibly from squirrels. Some Amanitas in Oregon have now been shown to hybridize, according to Dr. Lorelei Norvell and Janet Lindgren, making the Amanitas especially difficult to sort. According to toxicolgy reports, this fungus is responsible for more mushroom poisonings in Oregon than any other species.
On 11/24, specimens were small, golf-ball sized buttons. Today the buttons have enlarged considerably, with some larger than softball size. A total of nearly 15 specimens were clumped in close proximity to each other. Several appear to have been cut at ground level.

I didn’t take a panoramic shot of all the sporocarps, but they are all within a 2 square meter space at the base of a single beech tree. I think they may well be variations of the same species.
There are about 15 beech trees in this block. Only this particular beech tree has these Amanitas fruiting at this time.
