This was a difficult specimen to identify, which is why I did so in the end through molecular analysis. The sequences obtained were 100% identical to those deposited in GenBank for S. hornemannii.

Where is the annulus?

It looks more like Stropharia kauffmanii with the scruffy stipe instead of shaggy and the missing annulus.
