Moving a tree fern

I have a fern with huge leaves about 6yr old. I noticed that it has a grown a trunk underneath the leaves which looks like Dickensian Antarctia?. But the leaves dont altogether die back in winter and look coarser . What could it be and can I move it. Do tree ferns move easily?

 

Any chance of a photo Jean? David.

 

If it is a tree fern the leaves only die back if its realy cold, and the roots are in its top, you could dig a big hole around it and transplant it, they only grow an inch a year.

 

Thanks I will send a photo when I learn how to do it. I have managed to get it on digital camera but after that its one big mystery.
