The definitive source of info on Australian fungi?

 Hi All,

I'm keen to acquaint myself with the locally growing fungi in my region
(N.E TAS) and so far have only found very patchy/vague info on some (but
certainly not all) fungi here.

Many are quite obvious, such as field mushrooms, Amanita Muscaria and
the like... but 90% of them are unknown to me.

I'm mainly interested in determining which ones are edible - *that*
particular info is very difficult to find...

Any suggestions as to good books or online links (had little luck here)
very much appreciated.

BTW, I came across a patch of these at the roadside the other week:
