I’d say consult the Resupinate Denticulate/Hydnoid/Irpicoid Fungi list and compare for yourself. to me, the apically blunted/rounded teeth and overall look make Radulodon a good possibility, but it’s just a guess.

Sounds like a dinosaur or a good name for a dog…,

scope work required.

from Karen Nakasome:

“Radulodon is defined as a genus with a hyd­naceous hymenophore, dimitic hyphal system,thickening subhymenium, embedded cystidia,and globose to subglobose basidiospores. The five species accepted in the genus represents
a closely related group of taxa. The microbinding hyphae, found only in the subiculum or at the base of the spines and often overlooked, is a
significant trait of the genus.”

Any other hydnaceous crusts in the area that it could be, with just a macro ID?

very nice detailed photo, Eduardo!
