English: Mycena seynesii is a good example of what happends in nature. Many fungi organisms use the lignine and celullose present in leaves, branches, trunks or pinecones to feed themselves helping the ecosystem cleaning the ground, acting as sweepers. In this photo we see the "fruit" or reproductive organ of this mushroom, because when it has eaten enough its a good moment to move away to another pinecone. That's the way to scatter around of all the basidiomycota mushrooms, even those you use in pizza.
