Notes: On a lwan near Norway Spruce trees. No evidence of decaying wood, but can’t rule out buried roots.

Spore print dull orangish-brown.

Cut context stains dark. Gills stain brown.

Several similar Gymnopilus centered around junonius that are separated on very Murrill-esque features. G. imperiales comes to mind.

With a few colorful exceptions, Identifying Gymnopilus past section or even clade will, more often than not, require observation of specimens both mature and immature.

I am content to call this one junonius. Though, I would be thrilled if microscopy demonstrated otherwise.

We need more taxa from this genus on mo!

Thanks Rocky.

Just checked Mushroom Expert, and Kuo seems to agree with applying the name G. junonius to a variety of large clustered Gyms, with spore prints somewhat variable in color.

My own experience has been that G. junonius is generally more orange than this collection, and the spicy/licorice odor is pronounced. These mushrooms had no detectable odor and somewhat pale colors. Perhaps my concept of this type mushroom is too narrow.

The slow dark bruising/staining of context/gills is something that I associate with G. junonius.

You could check the cystidia, Pileus and gill trama and the cuticle. I am rather inclined to agree with G. junonius. The morphology you mentioned is treated as variable by Smith.

Spores in deposit: zinc orange OR duller rusty brown(ocherous tawny)

Habitat: conifer and deciduous logs, stumps, living and dead trunks and buried wood.

You can see that the ecology, in particular, is highly variable for this species.

I think these are not G. junonius…

because of… the lack of a spicy odor, the dullness of the spore print (G. junonius should show a bright rusty orange print), and the growth on the ground (presumably on buried wood).

Maybe something closer to G. luteus?
