Lyophyllum? There are Lyophyllum with some sort of interesting feature at all? That kinda suggests to me, they aren’t really Lyophyllum.

Some Lyophyllum, Inocybe and Entoloma spores look the same!

The new genus was created because the strange spore space for these. The spores are small 4-pointed, 4-sides triangular pyramids. I think someone posted a photo of the spores in another obs.
