Well, what you say is true…

Well, it is mostly agreed that what you say is true, that this is probably not H. aurantiacum as described, and as the name is used in east at least, that is just the name people have been using for this around here. It does look more like H. aurantiacum when young, it comes up all orange and puffy, but then starts to grow outward and the edges thin as it does, and turns more brown, until in age there is little orange left.

So, you can call it Hydnellum sp., or put it with other obs. of this species from this area by calling H. aurantiacum, or you can start to try and make sense of the CA Hydnellums! Try and get a copy of Tom’s student’s (post-doc?) monograph of Hydnellum and work up the stuff from around here. I’ve thought for years that the stuff from around here doesn’t go well with what I’ve seen described, which isn’t much.

I vote for “none of the above” option!

at least for now.

It certainly can’t be aurantiacum as described in Europe…we either need a new provisional name or…what? If everyone agrees to call a horse a cow, does it really make it a cow? How do we deal with something like this(a mushroom that we frequently collect) in a meaningful way? And the material that I have been calling “aurantiacum” here (prob. in error as well) has a much thicker and lumpier cap…this ones cap is thin and leathery.

consider Hydnellum auratile, described from Europe 1891 – or if you prefer a species described from Canada 1964: Hydnellum chrysinum. I can’t find any big differences in the descriptions.
Both have orange spines, while they are white in aurantiacum (until they turn brown from spores).

I agree with Douglas. Locally this is called Hydnellum aurantiacum.
See Mykoweb

I question H. aurantiacum.

The upper surface doesn’t look right for H. a. Much too smooth and brown. Flesh also perhaps a bit thin. Orange colors suggest H.a. would be a good place to start, looking for discussions of “look-alikes” that could then be checked out.

This is what we have been calling Hydnellum aurantiacum here is the west. It comes up more all over orange when young, starts to go brown from the inside out, until it is all brown when old. From other photos and discussions here, it seems there is the “real” Hydnellum aurantiacum in the east which looks different, and stays more orange. I’m not sure if Tom’s student (post-doc) covered this one in his Hydnellum study. And it would be good to see a copy of this Hydnellum study so we could find out… (hint… hint…).

A possibility, but I don’t know what else you might have in California.
Back here, we have it in rich, calcareous, coniferous forests.
