There was also tan oak and douglas fir in the area.

Well, Tricholoma then, not sure which one…

If it is not viscid, then it isn’t T. griseoviolaceum, and the cap isn’t fibrous enough for T. myomyces. It has to be with some other tree there, Tricholomas don’t grow with redwoods, there looks like some sort of broad leaf in the background of some of the shots? Or maybe D. fir was around?

But looks like some grey Trich. there are a bunch of them…

Cap was dry. Growing under redwood. The cap was approx 4.5 cm across.

In the series of photos posted, the top image does show entire mushroom. It was mixed woods oak and fir (and I believe may have been some bay) off the side of the road near Purissima Redwoods. Unfortunately I don’t recall the texture/feel of the cap (Alan do you recall?).

Looks like Tricholoma at least -

Need to know more here, was the cap viscid? What was the habitat, which trees were near by? Also when taking the photo, try to get the whole mushroom in the shot, to the get more details, instead of a series of close ups from different areas. It is hard to tell here the over-all shape of the mushroom here.

Cap Size

If you look at the finger and compare it to a cap size of 1.5-4.5 cm broad pileus for myomyces You would perhaps discount myomyces.
