Either Tricholoma ustale or T. dryophilum

The only reliable way to tell the difference is to put your tongue on the surface of the cap. If it’s bitter, then it’s T. ustale, otherwise it’s T. dryophilum.

A good place to start…

It looks like a tricholoma… I am not very good at these though! It looks kinda like a populina… that si something that can be common up here in Seattle but the habitat is obviously off.
T. dryophilum is common with Live Oak in California and starts out with a pale creamy colored cap that darkens in an irregular blotchy manner whereas T. ustale is uncommon (at least to me) and the cap starts out with a dark brown disc and brownish margin.
Also T. ustale is NOT farinaceous, but T. dryophilum does smell farinaceous.
