Mushrooms Growing in my bathroom

[Arachnapheria]

The below picture is of my bathroom ceiling. As you can see there is a fairly healthy crop of mushrooms growing there (which my landlord doesn't believe so am currently allowing to grow to prove a point). It would be useful if someone could identify them. Any help would be most appriciated. (sorry about the picture quality but only have a phone camera).

Impossible to say from that photo but we have seen a Coprinus species growing in these conditions before.

Welcome to WAB by the way

Hi

Yes the photo is very poor:

Are they like these fungi I have photographed in my cellar?

[Arachnapheria]

Yes they are, although a slightly more translucent version.

In which case, probably a Peziza species.

Hi

My photo is of Peziza cerea . This fungus is know to grow on damp plaster and mortar, and while not particularly dangerous to the structural integrity of a building (as far as I am aware but I am not a structural engineer!) its presence does however indicate that there may be some sort of damp problem.

yes Peziza cerea; I have known it in kitchens where I have lived, the gent's toilet at work, and on some carpet in the back of a friend's car (she wasn't fazed at all!)

not a structural threat, but an indication of excessive (and unwanted) moisture

cheers

Thanks for all your help everyone. Landlord is finally going to do something about the damp and I'm glad to here that this is pretty much the only reason for the growth.

Happy holidays to you all
