Is Eywa a fungal organism?

There's no reason it can't be through the roots - there is very little latency in an electrical signal. The gaps aren't particularly large anyway - the largest would be the roots seen among the mountains. Most likely, there are specialised nervelike structures that actually connect from one root to another.

Bio-Electrical impulses have no capacity to encode information. You cannot encode information within a single impulse...

No, but it can trigger a response. A synapse can act as what I guess would be most analogous to a logic gate, and can require certain activity levels to activate. A nerve can have multiple inputs to a single output. That is how differing responses occur.

Maybe funghi are sort of the synapses and individual plants are the cells/nodes/neurons?

This is possible - they could form part of the connection inbetween them, depending on how the signal is actually transferred through them. I wouldn't call that a fungal organism though, just that it is a component (individual fungi are also likely components much like any other plant is).
