Next time I collect what we are calling eburneus here on the west coast, I will do a KOH check. Good to have those simple tools at our disposal!

Are there macro diffs between cossus and eburneus, or just host choice and chemical?

A very good question, I haven’t been able to compare with a goat moth either. The smell has been described as sweetish or aromatic, but it’s not agreeable, and I don’t know what to compare it with. It’s a kind of smell that I only have learned to recognize in this species and Hygrophorus hedrychii (earlier interpreted as melizeus).

The names have rotated a bit in this group of species.
Hygrophorus cossus (grows with Quercus, no reaction with KOH) has been interpreted in different ways. What we have called quercetorum is now synonymized with cossus. It’s a species similar to eburneus (grows with Fagus, stem base reacting orange/brown with KOH).

Can you desribe the odor? I have no idea what a goat moth smells like. Also do you think this one deserves species rank?
