That's exactly how I feel.

Thanks for that info.

The reason I'm 100% sure even when only 30% sure is so that I can stay out of trouble. That kind of cave mold, while potentially dangerous to the typical human, but only if ingested, glows (quite brightly in some moist corners where its needs are best met) and is very helpful in that regard, as a little light never hurt a troglodyte, especially not one who ventures out onto the surface as often as I do. It if weren't for that mold, I would probably be as blind as a carnivorous cave-deer.
