Naturally occuring bioluminescence shows up in the fungal kingdom, especilally in the Mycena family. I have been working with Panellus stipticus since the summer of 2021. Below are the parameters and observations made about cultivating this species.
Fruiting timeline: 3-4 months
20% psyillium husk
5% tapioca starch
pH: 4 (add citric acid to water)
Supplements: calcium chloride, compost
Note: Genetics are everything. I have had the best luck culturing from plug spawn from suppliers who sell fruited jars of panellus stipticus. Wild cultures are also worth exploring.
