Control Tower without class D

In an earlier post I gave two examples of Class G towers that are
permanent in nature; FWS and GPM.

Class G control towers are NOT all temporary.

Class G towers are temporary in nature. When we set up fire towers
every summer they are most often in class G. I wouldn't worry about the
rules as we controllers are really lax at places like this. There are
no tapes and the level of traffic is low. The runway separation rules
are just a guideline. We're not sending someone around because we're a
mere 500 feet short on the separation. You're only going to know about
class G towers by notam.

In another thread, I have just read that there might be controlled
airports without having class D airspace, and pilots are supposed to
know this and know to contact the tower and stay of their non-class D
airspace if they are not in contact with the tower.

Can anyone confirm this?
