Part of the difficulty with your search for cristate forms may be linked to the terminology you are using. This Form of daylily is recognized as Sculpted cristate.

As Sue said beard is not a recognized term used with daylilies, it is botanically incorrect. That said I have seen the term beard used as a descriptive term for Sculpted cristates by some people even though it is incorrect.

Cristation, or crested would be correct descriptive terms to use.
While Lavender Blue Baby appears to be able to express cristation when used in some crosses, there are a majority of the 309 child plants that do not show or produce any characteristics seen in Sculpted forms. I wouldn't consider it a base plant for getting Sculpted cristates, but it may be useful in crosses.
Sigourney - cristate
Strikingly Dramatic - cristate, tender in the north
Aqua Tech - No, not cristate. Aqua Tech is pleated, but could work well with cristates.
Texas Feathered Fancy - cristate, although Sue has lost it I have had it growing in my zone 4 garden for a number of years.
Midrib cristation is the simplest variation of the cristate form. More complex variations can be seen in combination with pleated or relief subforms, all three Sculpted subforms work well crossed together.
