Identification: Inky oysters??

The other day I found a stack of 3 rather large mushrooms that I thought might be Oyster mushrooms. I pulled one out and it had really black gills. The next day I was amazed to find that they had all 'melted' into this big inky puddle. Any idea what they could have been?

 

truly impossible to ID without a picture, but since you're turned to a black globby mess, it was probably something in the Coprinus family.

 

Many of the Agaricus family will 'ink' out also? But as MycoRob said...impossible to know without a photo. :o(

 

Here are 2 photos that may not tell you much but still may be helpful.

 

I'll stick with my possible Agaricus?
Others may have an better idea........Glad to see photos! (my imagination without them stinks...lol)

 

Yup, clearly an Agaricus.

 

Thank you.
