Notes:
Growing in open grassy areas, sometimes fairly distant from trees.
Caps up to 7.5 cm across surface and somewhat viscid.
Weak striations up to 9 mm long.
Gills creamy white.
Spore print whitish to sl. creamy.
Spores not amyloid.
Spores 9.0-11.9 X 6.2-8.8 microns, ellipsoid and smooth.
Q(range) = 1.35-1.57
Q(avg) = 1.42 n=21
Odor not distinctive.
Found similar groups in other parks in the NW Louisiana area.
They were usually growing in groups on grass similar to an Agaricus, leading one to wonder if they were saprophytic(?)
10-16-18; A. spreta seems close, but the growth pattern is odd and Q values on these are quite a bit lower.

It will be interesting to see what these collections are, although I think a pale A. spreta would disappoint Logan Wiedenfeld and me.

The voucher material for this observation has been accessioned in our herbarium.

It strikes me that this might be a palled speciment of A. spreta. Well, we will find out in the not too distant future. We will schedule the collection for sampling.

Thank you very much for sending to us.

Very best,

Rod

Now that I see your data, I agree that the habit of the species and the shape of spores can be added to differences from Amanta spreta. I probably already mentioned on fb that I would like to see some of the material. Quite interesting.

Very best,

Rod
