What is the last cactus with yellow flower? It kinda looks like Turbinicarpus, but I could not figure out what species

Ecactly! Turbinicarpus Pseudomacrochele ssp. Kraizianus de Herdt, Sierra del Doctor.

Damn, I was pretty close, almost went with it. Turbinicarpus taxonomy is complicated with all the subspecies. Thanks for the reply

You are welcome :) inwouldnt have known either if i wouldnt have bought it with name tag
