Unfortunately this was the best I could do; it was incredibly tiny. I think it was about 1 cm in length. Upper Peninsula of Michigan on some moss at the base of a mature white pine tree. Hopefully that information helps; I know some fungi and molds can be quite particular.
Where's that slime mould specialist when you need them?
Nice shot.
No idea about this stuff, hopefully someone knows. Will take a guess on some sort of slime mould.
I have no clue what it is but I dig the color. All I see around my house are brown and shades of brownish.
You sure it's not a piece of used chewing gum?
Pretty sure it's not. This is an area that few people have easy access to and no one here chews gum.
I think it’s bird poop.
Embarrassing if so. But I'm not aware of any nearby food sources that would give them purple droppings. We also have a bird feeder in our yard and all the droppings on it are the normal color.
I’m not an expert so definitely take my comment at face value.
