Weird egg type shapes on my wet grass

Not got the greatest of lawns but boyfriend noticed this morning large patches of egg shaped stuff on the grass/moss/weeds!
It looks like small grapes, are they some kind of buf larvae? Seem quite large for bugs though, any ideas would be helpfuly.

Picture would help
Toadstools
I look forward to this time of year and all the different fungi that appear. If you want to mow the lawn sweep the fungi/toadstools off first to avoid making a sludgy mess of the lawnmower and lawn, but othewise just enjoy watching nature at work

They are more likely to be the droppings of an animal.
There's a photo of deer droppings on this page (4th photo on the page):

Yes, having seen your pic scrub the fungi idea (think I was misled by the buf/bug typo
).
Rabbit or deer droppings. Have you lost any shrub/rose leaves? If so I'd suspect deer, or an escaped sheep or goat.
