Yesterday I found mushrooms in the bathroom of the house on the wood,they look like cups and are brown, we are very concerned because have a 1 month old baby. I have pictures of them , and would like the advised of someone. What's the name of it? we think the micelium has to be everywhere because there is no fan in the bathroom.How dangerous is this?
Thank you so much for your answer.
These could be Peziza domiciliana, often found in bathrooms :-).
Not harmful per se, except for folks that react to fungal spores generally.
I don't think it is a wood decayer, but you might want to look it up to check.
