Be aware, usually fungus doesn't "die" in the sense of a plant dying, it just becomes dormant. If the lens is stored badly (ie in still air, in darkness and with any dampness or humidity) it could very easily start growing again.

As far as I know spores are everywhere in the environment so the chance for fungus growth is there from the moment you take your lenses out with the camera. What makes them develop or not are damp, dark, humid storage areas which is not the right way to do it in the first place anyway.
Just clean what you can (without taking too much risks while disassembling the lens) and keep the lens in dry places. Of course, using the lenses every once in a while is a very good idea, and that was what they were made for!
PS: I have recently bought some silica bags and put one or two inside lenses cases and storage bags. I guess it is another way of preventing humidity. Very cheap.

I'm a believer in silica gel, too, as a dessicant. Have been making my own bags from crystal cat litter, which is 100% silica gel, and paper towels; very inexpensive. Store all my lenses alongside these bags. Agree moisture is very bad for lenses, very good for fungal growth. |

Both have fungus so fingers crossed i can clean them, but I couldn't pass on a Tokina 17 for 25 quid, no way. I already have one but it;s in Konica mount so I can only use it on my NEX, I want this second one as it;s in PK and can be used on my EOS.

Yup, it's estimated that there are between 5 and 10 spores inhaled with every human adult breath depending on your location. Of the kinds that typically grow on lens glass with dust/debris as food; 50% to 55% Relative Humidity (RH) is required for germination (sprouting) and most strains like it cool (under about C 25˚). The idea that they like it dark is somewhat of a myth. Almost all lens glass will shield fungi from the UVc rays which they actually do hate - so even sitting on a window ledge during a bright day will not kill spores already inside the lens - assuming the lens doesn't heat up to C 30˚or so that is - and also assuming that the lens isn't made of quartz glass (I dunno of any that are tho!). Quartz glass will pass the UVc rays and kill the fungi - no other glass that I know of will.
If the lens is in a climate where 55% RH is common then typically sized (two or three of your thumbs in volume) Silica packets are pretty useless. And also such packets become saturated and then work in the opposite way - giving off moisture when humidity is lower than their saturate point - thus actually prolonging the amount of time fungi have to sprout and grow. Additionally many types of lens lubricants begin degassing and drying out at under 25% RH and new desiccant packs can and will bring the RH down to between 17% and 20%. So this is bad - physically for the lens!
But there is salvation! RH is co-related with temperature. The higher the temp : the lower the RH will be. And it doesn't take much! At about C 35˚ it's nearly impossible for RH to reach over 45% - in a closed space in normal weather where humans live. At C 30˚ to 35˚ usually an RH of 30% to 35% is maintained - depending on the climate and/or home weathering. At around C 25˚ to 30˚ an approximate RH of 45% to 35% is maintained.
By placing a small incandescent light (or a 50cm ultra-thin fluorescent tube) in a closed cabinet of approximately 100cmx50cmx50cm this temperature and RH coefficient can be maintained (indoors) during all seasons. This is how expensive lens cabinets work in fact. With the good ones, the power to the light bulb is switched on when RH reaches past your preset and off again when it is obtained. Usually that lightbulb is behind a rear or side panel so you don't see the light switching on and off - but hiding the light isn't necessary. Using a home made lit cabinet to about the mentioned specifications also will almost never bring RH down below 25% and if it does (like during a VERY dry winters days), just turn off the lights manually and you're good.
Here's my rig which cost me about $75 all total including the three untra-slim light fixtures on a cold and humid (C 12˚ / RH 65%) winders day (the perfect kind for growing fungi in lenses BTW):
With this setup so far (in 2 years) the RH has never gone over 50% and never under 25%, I did need to turn off the lights a few times in 2 years tho to prevent it from going under 25% RH. Also with the lights in these positions and the glass front like that it makes a really nice display and night-light in my bedroom!  |

I didn't know about cat litter silica gel - excellent idea, thanks. I had purchased several dozen small bags of the stuff and distributed them around camera and lens bags, boxes and drawers, but I find my local farmers' supply house stocks a make of silica gel catcrapcatcher.

You have captured the essence of my first thought upon seeing the post and photo. Wow! What a beautiful collection!!
My second thought, one I'm hesitant even to whisper:
This lucky lens owner needs to offer daily a prayer for absence of seismic activity. |

Got this puppy this morning for $30 at a thrift shop....(the aperture leaves are a bit slow to shut but there's no oil on them...and of course it's not a problem when used manually on the Canon)
...the focusing ring is nice and silky smooth, unlike modern AF barrels (and so a lot slower AF than the newer versions...but again not a problem for MF use)...
Not that it needs to be shown...but here's a quick test shot @5.6...100% corner crop (only sharpening is 3 on the DPP scale)...
