Wright Wrebbie!

I have seen Russulas on wood debris, especially coming up through bark mulch and chips. But Russula on downed well-rotten logs? Rare.

In areas where the chips are older, hard to tell where the Russulas start and the mulch (and associated wood-degrading fungi) take over.

I agree that this is what they strongly resemble, despite the poor photo quality and sad lack of an underside shot.

BTW Drew, I have seen Lactarius (and Russula) species growing on wood before….pretty common when the wood is heavily decayed. I am surprised that you haven’t seen them, too, in the PNW.

Thanks for the tip, Jerry.

I just looked at the largest photo I could get, and don’t see any whitish/greenish dots on the log.

Please look again. You may be reading something into this one.

The overall photo quality is not in focus; far too much that is fuzzy and not sharp. Cannot see any stipes clearly defined.

L. edodes grows on a great many wood types: oak, alder, birch, maple … Western hemlock. Problem with calling it L. edodes based solely on bedlog type is a great many other fungi also grow on the same woods. While working on my business plan, came up with 110 other wood rotters that like the same wood in my area alone.

If you look closely you can see small whitish/greenish dots in a a line running down the logs that look alot like dowel holes covered in wax.

Polyporus brumalis maybe

My first thought was Polyporus brumalis, but there is not much to go on with just this one photo.

Tried to verify L. edodes from photo

I don’t see it. I can see some scales near the pileus edges which might be consistent with L. edodes. Wood appears to be birch, at least to my eye. Birch does support L. edodes. But it also supports many other gilled wood loving fungi.

There is no photo of gills (which should be serated), and nearly no scales on the cap. Definately NOT Lactarius. But I’m less convinced it is cultivated. Where are the inoculation holes (if by dowell) or spawn application sites (if not by dowell)? Photo out of focus, I can’t see any details for the stipes at all.

Also, not much indication of scale present. These could as easily be scattered Flammulina growing on smaller branches as Lentinula edodes. To my knowledge L. edodes is not known to have escaped cultivation, although many have suggested it may have. Edaj does state it was “found on a log” but does not mention any size for said “log”.

I cannot verify this collection is L. edodes. That’s with 20 years worth of cultivation experience with L. edodes. A close-up of the gills; a photo of the stipe would have solved this by now (hint, hint).

would be one for the books.

Well, I don’t think it’s L. musteus

(don’t even know what that it is, never heard it used in CA before).

But it looks like it’s growing on logs that are cut and lined up together.
Almost like it was being cultivated.
Almost like it was… shiitake…
