This is a pigeon-hole for good quality photos of those mushrooms where gill colour is not known. These present puzzles as far as identification is concerned. It seems a shame to discard such photos and, for at least some, it may be possible to suggest an identification in the future.
The zz is there simply to force this group to the end of the alphabetic list of genera/species, since this category would be of no relevance to most users of Canberra Nature Map.
zz agaric (stem; gill colour unknown) is listed in the following regions:
Canberra & Southern Tablelands | South Coast | New South Wales North Coast | Hume | Barwon South West
