When the rainy season arrives, certain regions of Japan have these amazing glow in the dark fungi. A more technical description may be “humid ground hundreds of bioluminescent fungi grow, that thanks to a chemical reaction produced by an enzyme, emit a light that shines in a greenish tone”. I love the biology but more to the point these are mushrooms that glow in the dark, outside of Amsterdam. Bring it oooooooooon.
PS: Why should you take one of these to a party? As they are a ‘fun guy’ of course (I’ll go now)
