Fun fact. Lightning strikes stimulate fungi to produce more mushrooms. Some shiitake and nameko cultivators in Japan have started using electrical shockwaves and gotten dramatically improved yields (sometimes over 200%). Interestingly enough the idea came from Japanese folklore rather than this science

It's possible that this is an evolved response. Lightning hitting a tree will turn it into bark which is an excellent medium for white rot fungi. Lots of mushrooms might maximize the chance to get your spores there. Alternatively, it might mean you're dying soon and should seed out while you can.

We think of lightning strikes as rare events but when it comes to late-successional trees, they are actually one of the main disturbances. Some trees like Dipteryx oleifera have shown fascinating adaptations to lightning strikes. This tree is highly resistant to its negative effects and promotes the growth of many lianas (woody vines) that make it so when the tree is struck, so are many of its neighbors. After being struck it shows dramatically increased growth to outgrow its now-damaged neighbors
