I’m a master student in industrial design and for my master thesis I’m focussing on growing bioluminescent mycelium and searching for a way to use these in a product environment. The fungi I experimented with are Panellus Stipticus and Omphalotus Nidiformis. After long experimenting with different substrates and shapes, I’ve managed to get a decent success rate with a straw based substrate. The mycelium itself doesn’t produce a lot of light, but it’s definitly visible as a green-white color in complete or almost complete darkness and in the best scenarios can produce light for over a year in a closed of container without having to add anything. The picture below is an experiment using empty light bulbs. These ones managed to consistently produce light for about 5 months before dying.

Remarks or ideas are definitely welcome.
