Ha! I've bought you over to the dark side. 
Now these are a photographic target too, there goes your daylight hours
Nice photos.
Mt Tambourine has some exceptional fungi and I would encourage you to look at my mate Will Foresters site for inspiration.

The kit needs;
1 - a small soft paintbrush to get dirt off when the fungi is strong enough to take it.
2 - A white light Cree torch with zoom for the dark spots. Only about $5 on eBay or one of the Chinese stores online. Prob a copy, but it works.
3 - Empty 500gm rice into a biggish ziplock bag (double bag it for security) and it makes a great adjustable camera support down on the ground. Keeps moisture off too.
Sometimes it's good to go to Manual with a high f number for DOF (10~14) and adjust the shutter speed so the subject is just becoming visible, and then use the Cree for lighting.
That's all my secrets right there.
The 600D is the go to camera

The photos all used the rice bag and Cree torch. (Was that rude posting pics on your thread? I might need an etiquet lesson here).
