Observation - Mystery funghi growing in house - UK and Ireland. Description: My goldfish aquarium sits on a wooden base which was made from scrap wood and then painted. It must get damp underneath from spills and today we saw these little funghi growing up. They're very small,creamy-grey and black, papery and striped like palms.

My goldfish aquarium sits on a wooden base which was made from scrap wood and then painted. It must get damp underneath from spills and today we saw these little funghi growing up. They're very small,creamy-grey and black, papery and striped like palms. When I picked 3 up I got black 'dust' on my fingers. I hope that they can be identified from the photos using my phone! I'd be interested to see if they're something growing un-noticed in the garden and the spores have blown in (tank is about 3' from the window).
