Much much smaller.

12 to 15 cm? That’s huge! No, this one was, to my best guess, between 3 to 5 centimeters, including the rays.

works for me

I think the only other possibility in the genus would be A. pteridus, which is supposed to be considerably larger (see MycoKey), as in 12-15cm in diam. What was the size of this one?

Astraeus hygrometricus?

Matches the Wikipedia image quite well for starters: http://en.wikipedia.org/wiki/Astraeus_hygrometricus

In my guide, it mentions specifically that they are common in Arionza under pinyon pine, and this is exactly the location that it might be found. What do you think?

Will investigate further…

I’m grateful once more for the genus suggestion; I’ll try to identify a likely species and see what you and others may think.
