Spotting

Umm, well I couldn't really call it 'safe' because as I said it could be something completely different. I don't know of anything, but it would surprise me if there were no other organisms which could appear 'orange and fluffy' like this... That being said it does look likely.

This site isn't wholly scientific in its taxonomy anyway, so if you do stick an incorrect label on it, it's not the end of the world.

But one note about the label itself before you proceed. Whilst C. domestics was previously placed in the genus Coprinus, it has since been shown to not be closely related to the type species, Coprinus comatus. As a result a new genus was erected to house it and it's actual close relatives, 'Coprinellus'. All the species I know of which produce orange ozonium are in the genus Coprinellus. So if you do opt to give it a name go with 'Coprinellus species' or even better 'Suspected Coprinellus species ozonium' :-)

That does seem likely gully, think I would be safe labeling Coprinus spp.?

Could be something completely different but it is possibly the 'ozonium' of a Coprinellus species such as C. domesticus.

That is wild. Almost looks fibrous... Nice color!
