sure, Mycoacia uda has regular spines, but species like Mycoacia fuscoatra and M. nothofagi are really irregular. check them out!

I also think it probably belongs to another family, but I’m not sure where it is best placed.

as I’ve seen it, has more isolated, clearly defined “teeth,” like a resupinate Hydnum. these appear firmer and more lobed.

some Mycoacia species, such as M. uda and M. fuscoatra, turn bright purple-pink with KOH.
Mycoacia is by some authors considered a synonym of Phlebia.
I don’t think that this is in the Hymenochaetaceae.

vinaceous purple. A bit unexpected for me, since I rarely spend time with these crusty things.

no KOH test done, i take it?

ID or none, it’s a looker. a cross between a beehive and homemade candy corn…
