slime mold growing upon Stereum Hirsutum
It's eating Stereum?
Not eating, Rather using as a platform to grow upon
Ah, for creating fruiting bodies?
fruit bodies will form on the fungi, but i would think that the reason the mold ventured on the fungi was not to eat it, And that there was food favorable to the mold on the surface of the fungi, or that it has a better moisture balance and temperature to that of the wood
