This is really just a Panaeolus due to habit, habitat, taste and DNA sequences. It was split off from Panaeolus because the spores aren’t completely black and are ornamented – however that split didn’t withstand the test of time, and some Panaeolus have ornamented spores. Phylogenetically this is about 20 bases in the ITS gene from other species of Panaeolus, which isn’t much – many Panaeolus species differ by much more than that.

ITS sequences reveal that Panaeolina is really close to Panaeolus, and should not be its own genus. Morphological features such as the roughened spores are shared with other Panaeolus species.
