Have you thought about letting Moss into your life?

Three species together on a boulder in the car park. Nice sporophytes eh.

 I've got my toe in now and I'm hoping you're too British in spirit to slam the door. Choosing moss may sound relatively unexciting, but maybe you've not given it a chance. It's possible I've accosted you on a field trip, forcing a lens into your hand (hold it right up to your eye... no, hold it RIGHT UP TO YOUR EYE...) If so, you may have seen that tiny things, when magnified, can be just as fascinating as things more your own size. What are you, scalist? It's these little things that underpin the ecological running of the world. Pandas are all very well but the planet probably won't collapse without them (I'm not heartless really, I'm just very pro-moss).

Not only is it interesting to see the world from a different perspective for a change, you'll find it's not that difficult to collect a good number of species if you're looking for a nice mark. I've just been for a little trot round campus in the unseasonably warm weather, clutching my camera. I think I've got about 10 species already. With trips to a wood, limestone walls, somewhere watery, etc., you could probably treble that without too much hardship. Different places yield different species - mosses can be used as indicator species. The fieldguide from the British Bryological Society has a list of habitats and the species you tend to find there. 

Some moss looking super twizzly and waiting to unfurl in the rain.

 Of course the problem is more identifying what you've found, rather than finding it, perhaps. This is going to be more of an issue. I want to make a guide to the ones you'll most likely encounter first, but I'm not sure how imminent this will be as other things keep getting in the way. If you do want to do moss, you'll have to want to spend some time at a microscope, jotting down little drawings, and having a go with the (not always so friendly) keys. But Dave and I can find some time to help.

Nice red stems, distinctively curved back leaves - heaps of it literally metres from my desk
