I found this Coprinus growing out of a dead stump in a dark, damp corner of my property.
Spores are elliptical, almost sausage shaped and dark brown in DI water. The spore print was black.
Height of specimen is 90mm.
Cap was 40mm across.
Stipe was white and hollow, apex width 3mm.
Rained a lot the previous day. Dry and 45 degrees when I found it.
