FOUND THESE IN THE WOODS

[Marcos]

Hey there, i was taking a walk through the woods and came across these growing from some cow dung. I was wondering if you could help me identify them. 

Thanks!!

Deconica argentina is a species found in Argentina that grows on dung. But, this species is said to not form a ring on the stalk (despite there being a partial veil)   https://www.mushroomexpert.com/deconica_argentina.html . Another possibility is these represent a species of Psilocybe. But the spore drop seen on the one cap appears to possibly be jet-black. If so, then genus Panaeolus should be considered. Distinguishing between black and dark purple-brown spore print can be tricky. Obtaining a substantial print on a non-absorbent black surface is recommended. If the print is purple-brown, the contrast will show up against the black background. The mushrooms seen appear to be too old/dry to expect spores to drop.

Worldwide, there are numerous species of Deconica/Psilocybe/Panaeolus. IDing to genus --and perhaps ultimately to species-- likely requires microscopy.
