Found in Europe and Canada, it was described as new to science in 1984 by Austrian mycologist Meinhard Michael Moser.

Gills are dark gray initially, then develop a black mottling when the spores mature.

The gray to brownish stipe is 2–9 cm (0.8–3.5 in) long by 0.5–1.5 mm thick, and pruinose (covered with white powdery granules).

The fungus has been mostly found fruiting on the droppings of moose, although it has also been recorded on roe deer and reindeer dung.

[2] Moser originally published the name of this species invalidly in 1983 as Panaeolus alcidis;[3] this name is now considered an orthographic variant.
