Not sure on this one. All I can say was the exterior was VERY tough to penetrate. I wasn’t even sure it was a mushroom to be honest, but it was way to light to be a rock :)

I can’t seem to find any info on this species available on the web, and they won’t let me get past the first page of your reference online either.

Do you have any links, or copy/paste text? :)
