Could anyone identify individuals as good or bad? The black stuff looks pretty old and moldy.

Apologies for the crummy camera quality,





The stems are quite delicate and don't seem to go blue when i squeeze them.

Spore prints and a description of the environment you found them in would help a lot.

A spore print? I found them all in a cow field, all in old cow patties. Grassy field, quite humid and rainy for the past week.

Edit: Also, I found them in the northwest Florida region.
