on downed wood in mixed redwood forest.

5 cm cap, single fb. nothing I have seen before.

very difficult to rehydrate dried material.

there may not be spores.

a good candidate for DNA!


pale orange gills, sl. blue/green staining
decurrent gills, broad single attachment to wood.
dull orange cap, kidskin texture.
inrolled margin.

Based on microscopic features: no spore drop obtained (altho I tried)
Based on chemical features: odor like a Hebeloma: cocoa powder and radishes

no spores seen in smash mount/no spores dropped when fresh

this “agaric” had the toughness of a polypore! even after a dilute alcohol bath,
then a long water bath, the lone gill still wouldn’t crush. I finally had to chop it into pieces like a polypore! hyphae with abundant clamps, bundles of what appeared to be cystidia, some with swollen tips.

the odd cocoa powder odor remained even after drying! I broke off some of the attached bark, just to be sure the odor wasn’t from that.

any other possibilities?

Panus conchatus is the closest we’ve come.

But there is still that unique odor, which remains even after drying!

here’s a thought … rather than a somewhat trollish down vote (and of course its Agaricales, since we have no proof as to what it is, really), why not offer to do the DNA and prove it, one way or the other? If I’m wrong, beer’s on me!

of course I saw the similarity, hence my original description.

but here’s why it doesn’t fit: this mushroom was still in very good shape. The gills and cap were of a color, a dull orange, and not yellow at all.

the cap surface itself was unusual for a Pleurotus. And that odor was NOTHING like that of typical Pleurotus. My gut sez it’s something different.

I will try again to do the micro on these, but I still think that it’s a good candidate for DNA work.

AS to your seasonal evidence, here in CA, Pleurotus is an early fruiter, one of the first to appear after the fall rains. Not to say that we couldn’t have outliers. Climate change isn’t just affecting the polar bears!

Hi Debbie my reasons are as follows – Winter season, growing on hardwood, irregular shaped pale brown depressed cap with a wavy margin, decurrent gills yellowing in age, possible white spores shown in Photo #5 at the bottom near the margin, a diverse crowd all voting in favor of Pleurotus and your initial description of a “Pleurotoid Species,” all lead me to believe this could be Pleurotus, probably Ostreatus. Unless microscopy is performed I doubt we will ever know for sure which is reflected in my confidence level.

please tell me exactly which species of Pluteus this fb matches, and why!

I don’t know what it is!
By: Debbie Viess (amanitarita)

just that it is different.

I looked up your Neolentinus and Lentinus … similar but not the same. The texture and odor and color are wrong for Pluteus.


Whoa there, Debbie…

>It’s not Pleurotus

>Neofavolus is pored
Not N. suavissimus!

>Lentinus has serrated gills
Not L. levis!

What do you think it is?

this is the mushroom we were talking about on Saturday.

keep on throwing names against the wall … maybe one will stick!

It’s not Pleurotus, Neofavolus is pored, Lentinus has serrated gills.

Weird Hebeloma odor, too; it was in good shape when collected.

Dig deeper, guys and gals. ;)
