Tom is right, but I would like to add:
It depends on what is meant by "fruit on the same branch". If it means
successive fruiting, it is a different story. For example, Chondrostereum
purpureum is typically an early invader of wounds, and is followed by other
decay fungi like Schizophyllum, etc. This isn't really simultaneous
coexistence, I guess, but it isn't necessarily out-and-out competition, either.
