Recognized by sight: You need a scope to confirm. Would also be nice to know what it was growing on..
55% (1)
Recognized by sight: based on the (rather safe, I think) assumption that this is the same species as the one I scoped today. On large decorticated spruce logs at Cape Lookout, brought in by Judy Rodgers.
Based on microscopic features: Abundant amyloid, incrusted cystidia, long-ellipsoid spores.

otherwise I’d be there. i’m wondering if these:


might be the same. the micrographs on each are pretty worthless. i could find no spores or any significant structures when they were first scoped, but the smell was so, so distinctive.

it’s been a while since I smelled Chloroseptic.

show up at the Alameda Natural Grocery this Friday (tomorrow)…David will have the fruit body with him for his free talk on mushrooms, 7 pm.

just smelled it this afternoon. to my nose, it has an odd chemical root beer smell…kinda sweet but not so pleasant.

my daughter claimed that it smelled like chemicals and dirt.

micrograph added.

The smell

was fairly typical polyporoid, somewhat sour, a bit ‘fungal-earthy’, not remarkable.

please tell me you smelled it.

Nice work, Christian!

And obs 29499 is very likely to be the same species, Amylocystis lapponicus.
One more species of Amylocystis is known – unicolor from Borneo.

Thickwalled cystidia

should be abundant in Amylocystis, they are amyloid and sometimes incrusted at the apex. They are diagnostic if you find them.


good eyes everyone…

a few times this past week, including at Honeyman a few days ago… It has been growing on Sitka Spruce.

I… recognize that mushroom…
