Yes that is Steel-blue Entoloma (Entoloma hochstetteri).

Thanks Lucky Logan, I think you are right. Weird where things end up!!

Look at Entoloma hochstetteri. It doesn't say they're native to your area, but they are for New Zealand and India. Maybe a spore found it's way there.

Hey LuckyLogan, it was certainly easy to spot, and I've never seen anything like it before or since! Would love to know what species it is...

That is an AMAZING color!
