Phaeocollybia attenuata — possibly?

I am increasingly interested in these phaeos from chinquapin and manzanita habitats. These have the ‘fat rotund’ spores that characterize the attenuata complex (we have two molecular clades there), but the pseudorhizas appear to lack the criniform morphology that characterize the attenuatas I’m accustomed to.
Important needed details would be the cheilocystidial morphology and the stipe pith.

Would love to have a sample of this and the flimsy ‘benzo’ from the same area to examine.
