(Mods please feel free to correct me)
Scrubby, you should probably expand on your plans with the fungi book before anyone here jumps in to contribute...
I'm just thinking out aloud here, but something as potentially dangerous as fungi identification should be done by some sort of professional if it's to be relied upon by your readers. It would be like me writing a how to rock climb book, people could possibly die because of it. So, do you have a professional on board who will provide concrete ID's and be able to vet our reports to ensure accuracy?
I know it sounds a little safety-sally-ish but being a new member it's hard, for me at least, to gauge your experience and exactly where you are going with your posts. For example, and I hope this doesn't sound too harsh, but you are writing a fungi ID book and some random person on a forum with unknown qualifications has just been able to ID your photos, when one would expect you would or should already have information at your disposal (books, online resources, etc) to do the same and instead enlighten us.
We have a plant and animal database on the forum which could have had 5 either new or updated entries with your photos with some nice information from you with your fungi experience which would have been a shining example for people to then gain interest in contributing to your endeavours.
