thank god no!
that's the whole point of encrypting the communications and sharing the
public keys fingerprints inside tor sources.
a man in the middle can reroute traffic through his nodes but it will be
useless (except for sending your connections to /dev/null) as it can't
fake the private keys of each node.

In the italian wikipedia article, the author is wrongly assuming that
public keys for directory authorities will be exchanged through
Internet, so they can be easily spoofed, while they're already safe
inside your client.
