Comment: A few minutes with a specimen and a microscope is the only real way to resolve this. But, I must say that the picture looks a LOT like the picture of Contumyces rosella in:

.
Redhead et al. named an American variety of Omphalina rosella….var. vinacea. They do not mention the typical variety occuring in NA:

Omphalina rosella is transferred to the new genus, Contumyces in:
