Experts say new species of mushrooms could be waiting to be identified in Brisbane backyards after recent wet weather.
Queensland Mycological Society President Wayne Boatwright says the fungal kingdom is largely unseen until rain occurs and grows mushrooms.
Mr Boatwright encourages anyone who noticed fungi had popped to photograph them (without touching them) and post the photos in mycological Facebook groups, where experts could help identify them.
"Quite often we find new or interesting species in people's backyard … it will assist us in documenting true biodiversity," he said.
