Sorry, can't find anything but fungimap as an online resource, but saw these in my travels

.....
Freo fungi walk and talk (last year) here:
http://www.freofocus.com.au/news/html/fungi.cfm
Contact numbers given.
Perth Urban Bushland Fungi here:
http://fungiperth.org.au/index_bf.html
.. has been updated to include a link to this year's walks and workshops.
Edit: There's a link to identification tips, but they don't have a database... they recommend compiling your own - using books.

Good luck!
