I think that this material is very much related with that of observation 181564 from last year. The place of the observation was the same, a transition zone between chestnuts and pine trees: the first four specimens observed grew separated from the others about 25-30 meters, while the last six specimens developed precisely at the same place of my former observation cited above. As it happened last year I’m not sure they all belong to the same species (see the comments of that observation): the range of the colorations of the caps are similar to that previously observed and in addition there are a big variation in the size of the specimens, the bigger two despite of being young (the caps are not yet expanded) with a total lenght of 18-20 cm and caps diameter of 8.2-9 cm, whereas for the others these dimension are in the ranges 8-14 cm and 6-7.5 cm, respectively.
Anyone interested in seeing all the photos taken in the course of this observation can do it visiting the link (in the next two weeks):
I gave numbers to the specimens in a chronological order and each photo has the number of the corresponding specimen(s). I collected samples from the following specimens:1,2,3,5,6,9,10 and anyone interested in having part of it please let me know.

Naomi and I discussed the image again while we were processing the dried specimen. The large size of the central zone struck me as unusual in my experience. The large central zone resulted in their being only three zones. I’m used to seeing four or even five zones of color in this group. (We have at a few taxa with similar color distribution in eastern North America, although the there is less red in the brown zones in the species that I have collected in New Jersey.
that this is in the group of A.battarrae and A.umbrinolutea. dark edge of the gills and differently colored and concentric area on the cap are a good indicator macroscopically. Include also fulvoides among the suspects,just in case…
This material has been accessioned to Rod’s herbarium. We have scheduled it to be sampled for DNA sequencing.
Today I sent you the specimens 1, 3, 5, and 9 of this observation (together with some material from observation 222141 ). I hope you can compare it with the material I sent you last year, from _observation 181564 _.
Best regards and many thanks for helping me in this difficult task of “label” Amanitas from my mother country,
Spores taken from a spore print made over an chestnut leaf by a specimen growing side by side with Sp. 1:
(9.7) 10.4 – 12.7 (14.6) x (9.1) 9.9 – 12 (13.2) µm
Q = 1 – 1.1 (1.2) ; N = 52
Me = 11.8 × 11.1 µm ; Qe = 1.1
Very similar dimensions when compared with those in observation 181564.
