This is an interesting one! Ochraceocentrata has been VERY popular in the myco community in the past few years, formerly misidentified as Ps. Natalensis. They are very aggressive, resistent to contamination and suitable for all skill levels in the hobby.

This one is particularly interesting, looking like regular Ochra until maturity where the cap turns a darker hue! Some variants also have an issue with overlay, but these genetics do not seem to have that problemo.
