Two large clusters of these were growing on opposite sides of a dirt road. Habitat was mostly redwood with a few scattered firs. They were not closely attached to any tree that I could tell.
The gills were adnate to sl. decurrent.
Thee spore print was white, spores not amyloid and ~ 6.0-7.0 microns, essentially globose.
They look like the only ringless Armillaria in NA , Armillaria tabescens.
However, it supposedly is an eastern species that grows on hardwoods. The other problem is the spores, which are round and only showing a small thin apiculus.
I suspect I’m missing something obvious.
It was obvious!?!


Spores @ 1000X.
Basidia @ 1000X.
