It is a rather faint green glow. You need to adapt your eyes to the dark for about 15 minutes before it is visible. Once you do that they are pretty easy to see provided there are no other light sources around. I've only found the species on well-rotted hardwoods and once managed to get it to grow on some broken pieces of dead birch.

Eh, well I've got my log prepared and will be putting in the plugs tomorrow. Says it'll take 3 months to get any fruit, which will be in the middle of winter, but from the looks of whats going on in the package I don't think they'll stay viable until spring.

I'll just get a plastic tub from walmart to close them up in.

Checked in on them last night, and was greeted by this:

So I turned out the lights, gave my eyes a minute to adjust, and yup, all that white sheet was most definitely glowing.

Btw, does anyone know how much light is "safe" for this sort of mushroom? I've got it in a terrarium at the moment with some dirt in the bottom (to help retain moisture and humidity), and was wondering if it could stand enough light to put some moss in there too?

Panellus stypticus grows out there in the woods, so shouldn't mind some light.
