posed to the collector in the previous comment, I received an email which included, “I would have to say that the stem was on the underside of the wood close to the ground. The underside of this mushroom is at Observation 206092.”

Looking at obs 206092 we see what is clearly a Pluteus specimen. Nice call Rod! I was fooled by the warts atop the cap seen here. Looked like Amanita to me. Surprised to see this type ornamentation atop a Pluteus.

Actually, I think the ornamentation on the cap is little chunks of soil.

T. Nelson, was the stipe base…

of this mushroom inserted directly into the wood? Or was the stipe merely pressed against a log with the base wedged between the log and the ground?

I agree that amanitas can appear to grow on/through very rotten wood.

I didn’t base my comment on the image, but on the collector’s statement that the mushroom was growing on wood. Also, there appears to be a pinkish tint along the right hand margin of the cap; this could be the result of a light spore deposit.

Very best,

A closer look at the photo shows what appear to be pinkish gills. The cap has some debris on it looking like UV fragments, and that together with the cap surface color led folks to ID this a the blusher. So this could be a Pluteus after all. :) Another possibility is that a strictly mycorrhizal mushroom grew its mycelim on/through decayed wood, posing as a saprobe — I have seen this “behavior” in some boletes.

The log could have been used as a convenient perch to photograph the mushroom. The stipe was probably removed prior to picture taking. Just a thought…

I don’t know of an Amanita that grows on wood.

Check for pink spores. This could be a Pluteus.

Very best,


No underside??
