Observation 195038: Amanita rubescens group
When: 2014-11-07
(32.5261° -94.9587° )
No herbarium specimen

Notes: Several growing under mature oak in Sabine river bottom area.

Cap – 6.5 inches across. Dark orange-brown – muddled colors, pinkish tint. Large pinkish-tan-gray warts around bottom 1/3 of cap. Striations, 1/4 inch long.Flesh is relatively thin, well-stained brownish-pink from cuticle of cap.

Gills – White on fresh specimen, crowded, stained rusty-pink from cap around edge of cap. Connection to cap is shown in photos, slight attachment to stalk.

Stalk – about 1.25 times full width of cap if flattened out.Brown fibrous outer skin, gets lighter color at apex and at base. papery tan annulus attached. Becomes slightly bulbous at bottom, see cross section photos, roots at base. I couldn’t see volva material and I dug up two. Staining dark red due to insect damage. Partially hollow.

Spore Print – off white

Spore Size –
[20/1/1] L (9.0-) 9.2 – 10.4 (-10.6) μm x W (-) 8.0 – 8.7 (-8.9) μm, (L = 9.9 μm, W =8.4 μm), Q (1.08-) 1.13-1.22 (-1.25), Q=1.18 Broadly ellipsoid

Something happened to the whole lot…I think.

Very best,

even the “buttons” were collapsed in

even the “buttons” were collapsed in. ( see the two growing next to each other ).

Perhaps growing conditions caused early decay in all. I was assuming they were not extending as to their size, but this may not be true.

I’d like to find them again next year to see what they look like in good condition. All the blushers I’ve seen previously were much smaller.

Thanks for looking.

P.S. Congratulations on the profile article about you in Scientific American.

The first image has a collapsing cap that appears to be somewhat…

watersoaked over the stipe. Notice the rather well-defined region that is darker and wetter looking than the rest of the cap. My guess is that the center of the cap is decaying and hasn’t the mechanical strength to hold up the outer portion of the cap any longer.

Very best,

Yes, one specimen was aged. The other was a little on the immature side.

I labeled the photos as to which show the old specimen and which the young specimen.

You agree they are in the genus Amanita.

I’ll try to do a better job of collecting them next fall.

Hello, Linda Gail.

Some of these specimens are at least old if not senile and decaying. I think they all fall into the rubescent group for North America, although I cannot guess where they fit into the mix of taxa currently know imperfectly.

Very best,

Rod
