Is this a stinkhorn?

[Mano]

Hello Everyone,

Out walking the other day my wife discovered this (see attached pic) and obviously wondered what it is. It looks like a stinkhorn 'egg' but I cant find a picture of anything with this, rather beautiful, colour.
It was sitting on an oak bridge, which was a surprise to say the least. The oak bridge was new this year and so I cant believe it is rotting already, providing habitat for the stinkhorn. Unfortunately it got moved (luckily she just missed treading on it) and so there is no in-situ picture.
Does anyone know what species it is?

Any details gratefully received.

Thanks in advance.

was it squishy? it was clearly placed on the bridge deliberately - perhaps as a joke, if it was a stinkhorn egg and was to be found a little later in its development

cheers

Hello and thanks for the reply.

Yes it was squishy - I'm fairly sure the object wasnt placed there by anyone else as we are really the only people to use it.

A bit of a mystery.

Our chickens often lay eggs with a squishy shell which looks just like yours. Whereas a Stinkhorn 'egg' has a thin white membrane covering jelly beneath which is usualy quite visible, under which is the embryonic Stinkhorn.
Either way both are edible!!

It isn't one of those rather realistic rubber eggs that they sell to kids as erasers, is it? Did you try cutting it in half?

Hello everyone,

Thanks for the replies.
In response, the object is not a rubber! Trailing out of the back was a white filament with black dots in it - this is organic - I have never seen a chickens egg with a filament out of the back - but maybe I'm wrong and maybe it is an egg but we have no chickens anywhere in the area?
No-one would have put the 'egg' on the bridge as it is unused by anyone but us.
It seems that no-one can identify it!

Maybe a life form unknown to science!!

(yes, that was a joke).

Thanks anyway.

It's definately a birds egg, one that has not formed completely.

The shell looks thin and probably will not have received the final clour scheme therefore making ID nigh on impossible.

If it's a bird's egg then it could easily have been removed from the nest by either the parent or a predator and dumped/dropped/abandoned some distance away - which in this case just happens to be on your bridge.
