Please always include cheilocystidia, its very important. Also looking the pileipellis structure and for any interesting cells on the cap should probably be done with all lbms that are scoped. :)

The yellow is really faint if there, I don’t see it at all, it could be just the exposure. I think if this is B. titubans, it must of had a lot of sun exposure.

Maybe you can try the key in FAN6.
