Several heavily flocked Amanitas were seen in this area. Collected in one medium sized mature specimen, one smaller immature specimen, and one button that clearly would create a mature specimen larger than the other two.

Below are dimensions from the 3 collected, the largest seen was about 1.5 times the size of the mature specimen measured.

All were covered with large amount of flocking on the edges of the cap and stalk. The top of the cap had some flocking. The gills were ivory color in all including the button.

Smell – when cut – mild mushroom

Reaction to KOH and ammonia – no flash of color.

NOTE ABOUT PHOTOS: I’ve added additional photos with cut sections. All were photographed with the mushrooms against ivory stationary paper to reduce the glare from white paper.


1 – Mature Specimen:
Cap Diameter – 2.5 "
Flesh thickness center – 0.4 "

GILL – breadth – 0.5 " STIPE 2.1 " (from cap top to beginning of bulb). Thickness – top – .5 ", Mid -.35 " Thickness bulb top – .5 " Bulb Thickenss – max – .7 "

2 – BUTTON – total length – 3.6 "

Cap – 1-3/4 " diameter Flesh thickness at center – 0.35 " Stipe – thickness at top – 1/2 " Bulb – 1-1/5 " max thickness 1-7/8 length

SPORES: spore print in progress

UPDATE: I am removing spore images and specimen images for the “immature” specimen. It is not the same species as the other two. I’ve moved it into Observation 209313

Immature specimen moved

I moved it to Observation 209313. I went back today and found the area mowed. I only found one specimen which was fully open but small. The area is drying out and I don’t think there will much there until next fall-winter.

I obtained a spore print for the new specimen and a few photos. Unfortunately I started having camera problems.

Although I combined today’s material with the one that I removed, I am not so sure they are the same species.

It might not be a problem, but best is to get clean samples. Also, I’d like to swing back there before the heat dries everything up. I couldn’t do much on Saturday because of the impending fireworks.

Just a thought: If one specimen was immature and the other was a button,…

there would be a good chance that neither produced any spores at all.

Hence, there would be no confusion from spores being inadvertently spread about.

Very best,


collecting more

I plan to go back there early tomorrow and see if I can collect more specimens of each variety. It’s been 2 days but maybe I will be lucky.

The problem with the immature specimen and the button is that they were wrapped together and there is probably a mixture of spores on both.

separate MO#

Yes, I am planning to do this. It will be tomorrow though. I am trying to finish up something.

If it’s not too much trouble, could you please create a separate observation for the “immature” amanita. Since Rod thinks the material is not the same species as the other two fruiting bodies you posted here, it’s important to give this vouchered collection a unique MO#.

Thank you, Linda. We’ll see what we can learn from these creatures.

two different species
By: L G Price (LG_Price)
2015-07-06 15:58:35 BST (+0100)

I see that the one that I labeled as immature is actually a different mushroom.

(To see the labels you have to hover over the image).

It was growing about 2 feet from the one labeled mature. I had no time to look at them at the park. I was just photographing the first one (mature) when I was told I had to leave because of the fireworks. I scooped up the other two, grabbed my camera and left. The third one, the bulb was about 4 feet away.

I was planning to send you 1/2 of each.

Since one of the specimens in cross-section has pallid gills,

you might have collected two different species. The spores do seem to have some Q values ranging over 3.0.

Thank you for asking about whether I’d like some material. If you have material separated by gill color, I would indeed like to see some material of each gill color. For DNA the less mature material may work; but I will need some mature material of each gill color.

Very best,


Spore images added – A. rhoadsii?
By: L G Price (LG_Price)
2015-07-06 03:06:13 BST (+0100)

I put up a few photos of spores. I can’t stop and do the measurements right now, but a quick look seems to indicate that this may be A. rhoadsii.

Do you still want me to send some?

The yellow-cream gills in the button is typical of A. subsolitaria.
By: R. E. Tulloss (ret)

However, I have seen material in Mexico with the same color gills and same odor, but utterly different spores size and shape. The closest relation to subsolitaria that I know of in the southern U.S. is A. rhoadsii (another species originally described by W. A. Murrill).

I recall that the latter lacks a well developed skin on the cap, has a smell of decaying protein (called “chlorine” by some authors) and gills that are pale cream in side view. All three characters (as well as even narrower spores) distinguish rhoadsii from subsolitaria. I don’t think your material is rhoadsii…given the list of differences.

Very best,

Rod Tulloss

new photos, measurements and specimens
By: L G Price (LG_Price)

The specimens were in good condition. I’ve added more photos, measurements and discussion in the notes.

Specimens drying.

Flocking and collection
By: L G Price (LG_Price)
2015-07-05 15:40:59 BST (+0100)

This was heavily covered with white flocking on the cap and stem. The gills were turning creamy yellow.

When I looked at A. thiersii

Specimen 6 seemed to have a longer pointed bulb, but not to the extent these do.

I confess I got in last evening and left the material in my collecting bag, wrapped loosely in wax paper. I check and see if the specimens are still good in a bit. If so, I will dry. I had the specimen shown, a partially open one and a bulb.

If they seem good, I will split them in half and get more photos and measurements. Then dry and send half each to you and half to BRIT.

I need to split them to dry anyway.

I got run out of the park just as I found these ( they were setting up for fireworks ). If they are not good I can go get some more, tomorrow. I saw more. I also was thinking about going back for more of the strange little puffers I collected.

I read a bit about Amanita subsolitaria and don’t think it’s a match.

I am curious about your collection.

Hello, Linda.

Can you send me some of the dried material?

Very best,

Rod Tulloss

Amanita thiersii does not have a deeply radicating bulb like this material.
By: R. E. Tulloss (ret)
2015-07-05 06:08:57 BST (+0100)

This is certainly a species of Amanita sect. Lepidella sensu Bas. It might be Amanita subsolitaria, but it could be something with which I am less familiar.

Very best,

Rod Tulloss
