Observation 18460: Coprinopsis romagnesiana (Singer) Redhead, Vilgalys & Moncalvo

By itself in low spot near trail, not associated with anything in particular that I could see; CAP 3-4" wide, white with brownish scales and fibrils, thin disintegrating margin; GILLS gray turning inky black, free; STIPE long and slightly curved, white and smooth in top half, scaly/fibrillose in bottom half; SPORE black (visible on gill face at 20x); VEIL scales/fibrils on cap and bottom half of stipe all probably remnants of a universal veil?

Recognized by sight: The stature looks a lot closer to Coprinopsis atramentaria than Coprinus comatus. However, the cap ornamentation is closer to the true Coprinus.

The fibrils or patchy coloured streaks on the lower part of the stipe are pretty distinct, though I don’t know any deliquescing species off hand with that characteristic.

It would be really interesting to see a vertical cut through the stipe. True Coprinus has a thread running through the center of the stipe.
