Yeah, I checked the literature.

Although documentation of Cort species within the field guides is lacking, I expect that anything looking this much like C. armillatus would receive at least mention within comments under C. armillatus.

that I’ve done, there aren’t many Corts that looke like this one. Nice specimens though, and their habitat lead to my choice of species. Did a lot of work on this.

Corts are mainly difficult to get to species. But C. armillatus is one that I often feel comfortable naming. Your collection looks like what I’d call C. armillatus. The bright red “bracelets” on the stipes and occurrence in birch woods are good indicators.
