It may have been planted but I am unsure.
Taken at a friend's house. Sorry for the very bad quality.
Is it some kind of structure made by Life or is it a plastic thing ?
It's a trap !
In a house, behind a clock. Daytime. You can see some other smaller organisms, maybe nymphs ?
From Luci SG that asked for ID help. A more accurate georeference will be given soon
I put order Physarales because the only two species I could think of were both in this order: Fuligo cinerea and Mucilago crustacea. It was in the garden around the house of my grand-mother. I guess the soil is calcareous and rich if it is of any help.
The top ones. I posted another observation for the bottom one.
I am not sure about the ID but this is only thing which came to my mind.
