Those photos show a lot more disassembly than you should need. You'll regret unscrewing the focusing helix (14th photo, large silver-colored threads). If the fungus is visible from the front, in front of the aperture blades, slide the hood forward. Focus to the minimum distance, 6 or 7 feet I think. Then grab the barrel just above the focus ring grip and unscrew it, counter-clockwise. The front group of elements comes off after a lot of turns. The inner surfaces on the camera side of the aperture blades are now somewhat accessible if the aperture ring is set to f4.

If the fungus is further back, you can use a lens spanner or improvised tool on the slots around the rear lens element. Sometimes the whole group is in one threaded carrier, and sometimes each element comes out individually.
Thank you so much. That worked a treat. I have cleaned most of the fungus. I just need to disassemble the glass further est from the camera now - I might by a tool from ebay.
